Pros and Cons of Native and Hybrid Apps https://teckstack.com/native-vs-hybrid-app https://teckstack.com/native-vs-hybrid-app#respond Thu, 09 Mar 2017 13:13:39 +0000 http://teckstack.com/?p=5102 When you commence the process of app development you are faced with a plethora of questions. Should you build an app for Android or iOS or both? The one thing which should be clear in your mind is that the app which you build should offer a superb user experience lest the users will not use it. It has been seen that users tend to use a mobile app just once and if they do not like it, they will not use it again.

Just 16% of users give an app a second chance. So, what is important is that users get a superb experience when they use a particular app.

There are basically two kinds of apps:

  • Native Apps
  • Hybrid Apps

Native Apps

These are a standard in mobile world. Native apps are basically written for a specific mobile operating systems, be it iOS or Android and they work best for the chosen platform. As native apps are made for a particular operating system, they can be only be accessed via a dedicated app store. This means Android application can be accessed just by Android users and is made using Windows, Java, C++ etc. Native app which is made for iOS application makes use of XCode/Objective-C. Native apps are native to operation system of the user and therefore built as per those guidelines.

Pros of Native Apps

  1. Complete Device Integration
    With the native apps, it is possible to take full advantage of functionalities which are presented by the mobile devices such as: calendar, camera, GPS, microphone so many more. This offers experiences which hold more relevance contextually. The users get to enjoy more features which he would otherwise have no access in case he/she was using a hybrid app.
  2. Easy to find in App Store
    It is easy to access a native app via app stores. In case your app is visible in Google Play Store or the Apple App Store this means your app will ultimately catch the fancy of the users and enable you earn big bucks.

  3. Superior UX
    Android as well as iOS apps present a very good experience to the users by adhering to precise UI standards which are followed by apps created for such platforms. Because of this navigation becomes easy and users are able to follow systems in a hassle free way. Native apps thus facilitate smooth as well as descriptive transitions offering user with a seamless experience.

  4. Do not necessitate internet connectivity
    Depending on what functionality they offer, native apps do not always call for internet connectivity. This is a good feature as users will be able to use the app even at places where there is no WiFi. A hybrid app cannot be accessed where there is no Internet connectivity.

  5. Superior performance
    As native apps are developed keeping in mind only single operating system, they offer better performance than the hybrid apps. In case you wish to create a high-performance app, go in for native app.

Cons of Native apps

  1. Need of more developers
    Building a native app calls for more effort as well as time. Also, you need services of more developers for this task. It is vital to make sure that they have necessary skills as well as for developing the apps.

  2. High Development Costs
    Native apps are any day more expensive than hybrid apps. They are quite complicated and necessitate multiple code bases which have to be developed by the developers. This leads to higher expenses as compared to hybrid apps which need a single code base.

Hybrid Apps

Hybrid applications on the other hand are websites which are packaged into native wrapper. These are as a matter of fact latest HTML5 applications. The biggest benefit of designing hybrid app is dependable, cross platform UI which is in sync with maximum number of devices. This mobile app development system is less expensive but this cannot be put to use for every kind of app.

Pros of Hybrid apps

  1. Fast development process
    Hybrid apps do not necessitate the presence of too many developers to build the app. This is a good thing in case speed is a vital factor in your app development program.
  2. Apt for apps with small release cycles
    In case you wish to regularly incorporate changes in your app, Hybrid app development is a very good alternative. Only if the change is huge will the users require updating the app. Updates can be put on the page which the user loads from the server. This way the users will find it easy to navigate through the app.
  3. Optimum for BYOD Programs
    Hybrid apps are ideal for BYOD programs. They work across various platforms as well as devices, this way you are freed from the tension that your employees will not be able to access the app just because it is not compatible with their operating systems or devices.
  4. Reduced development cost
    It falls cheaper to build a hybrid app than a native app. You do not have to undergo the problem of getting separate apps developed for separate platforms i.e. iOS and Android. Rather you will have an app which is ready for both platforms.
  5. Minimum requirements
    The developers do not have to learn separate languages in order to build a hybrid app. Hybrid apps look as well as feel quite like a native app and can be created with just one language that is C# which is bolstered with frameworks such as PhoneGap wrapper or Cordova.

Cons of Hybrid apps

  1. Not impressive UX
    One of the biggest flaws of hybrid apps is that they fail to present a complete native-like feel. And if users do not get an impeccable first experience, their likelihood of trying the app again falls down drastically.
  2. Reduced efficiency
    As compared to native apps, Hybrid apps are generally slower. Because of this you are not able to have meaningful as well as smooth transitions.
  3. Presence of lags as well as UX issues
    As hybrid apps do not present a seamless experience that is characteristic of native apps it can create serious performance issues in high-performing apps as well as games. Users will face lags and because of this, they might even leave your app.


So, these are few of the pros and cons of native and hybrid apps. Plan your need, weigh the pros and cons of each category and go in for app development accordingly.

Bower-Installer - Deploy Bower Dependencies for Github Pages https://teckstack.com/bower-installer-deploy-bower-dependencies-github-pages https://teckstack.com/bower-installer-deploy-bower-dependencies-github-pages#respond Tue, 31 Jan 2017 21:24:17 +0000 http://teckstack.com/?p=5076 Bower is one of the popular Node package, which has changed the traditional way of managing frontend dependencies. If you haven't explored it yet, you are lagging behind the trend!

Why Bower (in shorts)

Few years ago, when we have to start a new project, we used to create directory structure manually and download all required assets like JavaScript and CSS files from the web. Below is a standard folder structure considered by majority of the developers.

/ css
    - style.css
    - bootstrap.css
/ js
    - bootstrap.js
    - jquery.js
/ img
    - logo.png

Bower can be initiated by running bower init command at the current project destination. Then it would create bower.json file with basic configurations.

Bower Init
Bower Init
Bower Install Dependency Configuration
Bower Install Dependency Configuration
Now you are ready to install frontend dependencies using bower install {package-name} (i.e.: jquery). Any dependency installed with --save will be added to bower.json file under dependencies section (as seen in the screenshot).

Bower Install Package

Github Pages (a little)

Github.com is the most popular site allows developers to host their code for free. Github has popular feature called Github Pages, where project related content can be published for demonstration purpose with browser accessible URL and that is without any cost. Even more, Github Pages can be configured with custom URL to look more professional.

Example of Github Pages:

The Problem

Now we gained enough knowledge to understand the benefit of using Bower that to avoid dependencies and make it easier to distribute the project source-code with minimal size.

So considering above statements and per the best practice, we usually don't push bower_components folder to the Git remote repository (as it can be download all at once by running bower install). So the problem is - HOW TO MAKE THOSE DEPENDENCIES AVAILABLE FOR GITHUB PAGES?

The Solution

  1. As a solution we can either create a new folder manually and copy paste required JavaScript and CSS files and push them to Github repository. But I guess then there is no meaning of using Bower.
  2. I did little research and found bower-installer

What is Bower-Installer

Bower Installer is another node package which does magical thing. It allows developers to define a new section inside bower.json file.


npm install -g bower-installer
Bower Installer Configuration
Bower Installer Configuration

As seen in the above image, we have install section. Under install, we are passing "path": "assets", where "assets" is a folder name that we have to create to be considered for all frontend assets required to be pushed from bower_components folder.

sources is required when you want specific files. Like in case of Bootstrap for some reason I want to copy only .css file then I need to define the path for that file under sources as stated in the screenshot (by default bower-installer would copy .less file from Bootstrap).

After the changes we made inside bower.json file, we are good to run the below command, which will automatically takes .js and .css file (and NOT the entire folder from bower_components)

Bower Installer After Run
Bower Installer After Running

Comparison - bower_components Vs bower-installer

Bower Vs Bower-Installer
Bower Vs Bower-Installer

As we can see the difference in above image that bower_componet has entire structure with its own bower.json and other files, which are infect not required for project.

On the other side, under assets folder we can see only one jquery.js file which has come after running bower-installer command.

So to sum up, which UI was breaking due to non-availability of files inside bower_components folder, can be fixed as needed files are available in assets folder and even the same can be pushed to the remote Git repository.

I hope this article would help you. If you have any question or suggestion, do not hesitate to share in below comment section.

How You Should Start with NodeJs https://teckstack.com/start-with-nodejs https://teckstack.com/start-with-nodejs#respond Sun, 20 Nov 2016 06:20:58 +0000 http://teckstack.com/?p=5069 NodeJs is powerful JavaScript runtime which enables ability to run your friendly JavaScript on server side. If you are advanced JavaScript expert then understanding NodeJs is easy but the same will be difficult for others who are at the beginner level of learning.

This article will focus on step-by-step guide to start with NodeJs.

I assumed that you've already gone through what the hell NodeJs is and what are the different ways to install it on your machine.

Okay let's get started now!

Step 1: Consoling and Confirming Code

As a JavaScript developer, it's a good practice to test your code in a browser console before server deployment.

  1. We need a file to run code in NodeJs. So first we will create a file index.js (can be any infect, but it's good to keep meaningful name).
  2. Put below code inside index.js file.
    var aboutMe = {
        fullName: "Kushal Jayswal",
        expertise: "UI/UX and Frontend Technologies",
        currentExperience: "4+ years",
        myBlog: "https://teckstack.com",
        personalSite: "https://kjayz.com",
        githubTwitter: "@kutec"
  3. Use node index.js code in command prompt to check whether code is correct or not.
  4. If everything goes well, it must print the file content in command prompt.

    Start With NodeJs Output

Step 2: Creating Local Server

NodeJs is an environment and not a framework. So there is nothing ready to use except API. But to use APIs we first understand each API in depth. Like all NodeJs application needs a server and we can create a local server using http module using its createServer() method.

In NodeJs, require is the most used keyword because when any internal or external modules needed, you have to include them in your file using require.

var http = require('http');

Why we required a local server?

I understand your feeling. As a frontend developer you never dealt with server. In the past you might have worked with developers who write code for servers in Java, Dotnet, PHP, etc. But with NodeJs, though you are using JavaScript, you required a server to send and receive requests from client to server and vice-versa. I know the explanation is not so technical but enough to get the idea!

Now let's move to create a local server using http module in NodeJs.

var http = require('http');

var requesrHandler = function(req, res){
     res.writeHead(200, {
         'content-Type': 'text/plain'

var server = http.createServer(requesrHandler);

server.listen(3000, 'localhost');

Code explanation

First we have included the module http using require keyword. Then we have defined a callback function which accepts 2 arguments req (request) and res (response). writeHead(), end(), createServer() and listen() are various methods of http module.

listen() method used to define a port number for the localhost.

Run the server

As per the Step 1, you need to put the code of this section into index.js (or server.js) file and then run node index.js code in command prompt. If there isn't any error, it will give blinking cursor in the command prompt and then you have to open a browser and hit the url http://localhost:3000.

As an output, you will see whatever mentioned in res.end('Welcome');.

I hope this article will help you to get started from scratch with NodeJs. If you have any doubts or suggestions, please put your comments below and make it loud.

Different Ways to Install NodeJs https://teckstack.com/different-ways-install-nodejs https://teckstack.com/different-ways-install-nodejs#respond Sat, 17 Sep 2016 14:48:41 +0000 http://teckstack.com/?p=5050 NodeJs is another JavaScript written for servers. But to learn it flawlessly, you should have advanced JavaScript concepts. Also having basics of HTML and CSS would help you to understand templating part.

This article would cover up the NodeJs installation stuffs. But before you start, I would recommend to read previous article - what the hell NodeJS is.

Okay let's get started now!

There are 3 different ways you can install NodeJs on your machine but it really depends which is more suitable as per your project need. So, let's see all one by one.

3 Different Ways to Install Nodejs on Your Machine

  1. The .MSI (Installer Wizard)
  2. Node Version Manager (NVM)
  3. Compiled Source (Official NodeJs on Github)

The .MSI (Installer Wizard)

Nodejs Installation Wizard
Nodejs Installation Wizard

You can download .MSI installer from the official site as per your machine configuration. The installer is designed to set up all things automatically including environment variable and this is the most recommended way to install NodeJs on your PC.

Bad Things

  • You cannot change through the versions easily. If you want to switch then you have to rerun the installer.

Node Version Manager (NVM)

Nodejs NVM Installation
Nodejs NVM Installation

Node Version Manager (NVM) is another way you can setup node locally. NVM is beneficial if you have to switch Node versions frequently. Also it is recommended for deployment team.

If you use Windows PC then you can head over to nvm-windows, which allows you to install NVM using wizard.

Bad Things

  • Before actual installation of Node you need to set up NVM first.
  • Also, whenever you switch the version, you have to re-install previously installed global modules.
  • Moreover, you need to be familiar with CLI related commands.

Compiled Source (Official NodeJs on Github)

Nodejs Github Source
Nodejs Github Source

If you are a geek and want to get all the latest from the core team of NodeJs then you can download compiled sourced directly from Github.

Bad Things

  • You would download the latest code from the core NodeJs team, but you have to compile it manually in your machine.
  • Also, it would take longer than .MSI and NVM as you have to build and deploy the code manually.
  • It is not suitable if your project requires frequent version change, because each time you change the version, it needs to be reprocessed in terms of compilation, build and deployment.


Well! Finally, everything is upto you. As a frontend developer, I would prefer the most easiest way and that's .MSI wizard installation. You may have different choice suitable the best to your working environment.

If you could share more ways to install NodeJs, it would be great help to the community. Kindly add your comments below in comment section.

What the Hell NodeJS Is https://teckstack.com/nodejs-is https://teckstack.com/nodejs-is#respond Sat, 13 Aug 2016 19:31:59 +0000 http://teckstack.com/?p=4946 Before we start on the conceptual part of the NodeJs, I would like to share a short story that many frontend developers might have come across.

Short Story

Ritesh is a Lead Frontend Developer who got fantastic idea to set up his own startup business. He has the business plan ready with him and now he wants to meet different fund-raisers to get investment in his project so that he could actually start-up.

Before meeting with investors, Ritesh should have working prototype (demo application) to showcase project features and overall look and feel to investors. (Do not forget that Ritesh is a frontend. So, he can do certain things and but not all. Let’s differentiate…)

Ritesh Can

  • Work on branding and design related stuffs like logo, Photoshop (PSD) layouts, etc.
  • Convert Photoshop designs to HTML, CSS and JavaScript markups
  • Even create a data driven prototype using JSON
  • Marketing his product/project/service
  • Manage teams of developer

Ritesh Cannot

  • Design a database structure
  • Write code to connect a database with his application
  • Write code for the server using PHP, Java, Dotnet, Python like server-side languages

Here, “Ritesh Cannot” is one of the reason when NodeJs comes in a picture.

So, What Exactly the NodeJs Is?

NodeJs is not a magic. It is just an a JavaScript environment with different purpose. Node is very much dependent on internal or external packages. Also, the NodeJs API is pretty much tiny. So once you start learning, it's tough to get rid of it :).

To develop a project with NodeJs, having additional framework that can use Node.js methodologies and build over it, is advisable. Express.js and Koa.js are the most popular NodeJs frameworks in this category. I recommend Express.js because it provides easy routing mechanism without much hassle.

NodeJs Definitions

NodeJs® is a JavaScript runtime built on Chrome’s V8 JavaScript engine. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient. Node.js’ package ecosystem, NPM, is the largest ecosystem of open source libraries in the world.

In software development, NodeJs is an open-source, cross-platform runtime environment for developing server-side Web applications. Although NodeJs is not a JavaScript framework, many of its basic modules are written in JavaScript, and developers can write new modules in JavaScript.

My Personal Definition of NodeJs

#NodeJs is an environment to run #JavaScript on the #server and off the #browser - @kutec
Click To Tweet

NodeJs Is

  • A server-side JavaScript environment
  • Somewhat similar to Google Chrome console
  • Another CLI Tool
  • Asynchronous, Non-Blocking
  • Single Threaded (Event Loop)
  • Non Buffering
  • Super Fast

A Server-side JavaScript Environment

JavaScript is primarily a client-side scripting language. But NodeJs has special power to make the same JavaScript available on servers too. That means we can now code entire application using JavaScript itself, doesn't matter it's server or client. However, NodeJs is not a framework, it's just an environment. Because we have to do all things manually.

Let's say, if we want to write some code for server then first we need to create server and then only we can do the further manipulation. Framework has many things pre-exist which we can use instantly to save extra human efforts in development but that's not the case here with Node. Of course Node APIs are there and the NPM community is vast enough to expand your thoughts.

Somewhat Similar to Google Chrome Console

If you are familiar with Google Chrome browser then you must come across the developer toolbar. There are many similarity between Chrome console and NodeJs console because both are using V8 JavaScript engine. So there are many things available in both but not the all. Let's compare few of them.

Chrome Node.js

Here we have a quick comparison with known JavaScript keywords. As you could see that global, require, module and process are available window, location and document are available in browser console but not in Node console. The same way global, require, module and process are available in Node console but not in browser console.

However, the console.log is the most common keyword working in both the consoles.

Another CLI Tool

Using Node is required to be more familiar with Command Line Interface (CLI). It might be inconvenient for developers who are not used to with command line. But once you get familiar with commands, I am sure it will be more fun and faster than your usual development flow.

However, there are many addons/plugins available which you can install into your IDE. I have used Bracket's Node.js plugin and it was great experience.

Asynchronous, Non-Blocking, Single Threaded and Event Loop

These all are technical terms and mostly concern with the performance.

Asynchronous is an execution approach which doesn't wait to be finished and move to the other execution. So if we see traditional synchronous execution, it waits for any request to be completed and then only move to the next execution in the queue. So asynchronous is more faster.

Asynchronous uses similar approach that we have in HTML5 Web Workers for scripts.

Asynchronous Email Process
Asynchronous Email Process

Non-blocking means as and when executions happen, it will return immediately with whatever result it has without putting your thread to sleep (with high probability).

Event Loop is another approach which always waits for something to happen. Here "something" is an event. If event occurred, then we can define the next step with a callback function. Callback function is important because it give instruction for the next execution. If we don't have callback function then it will continue iterating the same event loop infinitely. However, we can minimize the iterations using setTimeout() method.

Node Js Event Loop

Non Buffering

A Buffer is a chunk of memory, just like you would have it in C/C++. You can interpret this memory as an array of integer or floating point numbers of various lengths, or as a binary string. Unlike higher-level data structures like arrays, a buffer is not resizable.


Super Fast

This post is more towards the theoretical concepts of the NodeJs. I am sorry if you feel bored about it. But yes, this would surely help to start with NodeJs. Working on Node projects is going to be fun.

My next post will be on - Getting Started with NodeJs.

Some Negative Factors of NodeJs

If you are going to consider NodeJs for your next project then you should be clear on the negative side of the NodeJs. Below is an interesting thread on Quora, you must read, before making any decision on the Node.

What are the disadvantages of using NodeJs?

A Quick Comparison - WordPress, Ghost and Medium https://teckstack.com/comparison-wordpress-ghost-medium https://teckstack.com/comparison-wordpress-ghost-medium#respond Thu, 04 Aug 2016 18:22:17 +0000 http://teckstack.com/?p=4949 If you are involved in the field of blogging, there are many platform option for you, viz., WordPress, Ghost, Bloggers, Tumblr, Medium, Squarespace, Wix, etc. But to become a successful blogger, you must be looking for a reliable and easy to use a blogging platform to launch your new blog. I hope I'm correct?

So, today, taking a look at all the incredible platforms we have found, three options for you. WordPress, Ghost or Medium? All the three platforms are not perfect, but each can serve a definite purpose. So depending on the nature of goals and your purpose, you may choose the ideal platform for you.

Here is the discussion of the WordPress vs. Ghost vs. Medium. Which one is best?



I don't think so WordPress requires any introduction if you're a regular user of the internet. It is one of the most popular building platform and excellent content management system. It nearly hosts 32% of all the websites and blogs on the internet. It has powered websites more than blogs like eCommerce websites, business websites, news sites, etc.

WordPress websites are available in two flavors:

  1. WordPress.org
  2. WordPress.com

Now you must be under the state of confusion between the two. WordPress org. is self-hosted, and provides the privilege to download and install anything on your server. WordPress.com, however, runs from .com servers directly. It provides limited options, such as it does not allow to download any custom plugins but possess theme options.

WordPress is popular for its simple user interface and its flexibility. Due to its extreme customization possibilities, it is a perfect choice for professional bloggers. The best out of it is that it offers a great, ready-made community support for its users. However, the great elements such as SEO metadata and custom content types can only be found at WordPress.org. It is important to note that, WordPress is not only free to install but is also supported by great free as well as paid Themes and Plugins.


Ghost Blogging Platform

Ghost is a simple and a clean platform which relies on the crisp and least user interface. We can say that Ghost is a simple version of WordPress. Unlike WordPress, Ghost does not have power a wide array of websites. It is a simple blogging platform for bloggers.

The platform can be downloaded free of cost. The hosted – Pro – version stands at $8-$200 depending on the number of blogs you want to run and the traffic volume one is expecting. The platform uses markdown rather than WYSIWYG visual editing.

Similar to WordPress, it also comes in flavors:

  1. Self-hosted version, which is free to download and use
  2. Hosted version

However, Ghost does not offer a free hosted plan or limited in the hosted version in any way. It helps to upload content or themes with the use of FTP. It is considered best for bloggers, who are crazy for the use of newer and freshest technical solutions. Its USP is minimalism, which can be seen in designing and functioning where the user can create and edit posts.


Medium Blogging Platform
Medium Blogging Platform

The medium has grown in popularity a lot over the last few years. It defines itself as "a community of readers and writers offering unique perspectives on ideas large and small.” It is true because it is admired for publishing blogs, stories and articles. It is well suited for serious writers, focusing on highly high quality niche-centric topics.

Medium is a hosted platform and does not give permission to download anything to its users or run it on your servers. It is best for hobby bloggers as it gives instant readership to the users stories.

The major advantages of using it give free custom domains, sub-domains, SSL, etc.

The Verdict

The answer here is not simple and direct. If one is looking for a basic setup of social sharing as well as SEO, and platform for publishing post simply, Ghost is the best answer for you.  It has the cheapest plan at $19 per month and topped at maximum 25,000 page views in a month.

Whereas, WordPress is considered as king in CMS. One can run it on $250/ month cloud server and on $2.5/ month shared web hosting. It gives the perfect choice to build professional blogs. While Medium is a viable option for people to explore and read your work, and leave feedback. However, it has a very stiff budget and better for company blogs hosted outside of the company’s website.

I hope, you're clear with all the three platforms' usage. Leave the comment below for the platform you like and share your experience with the community.

Create Status Indicators Using Sass Mixin https://teckstack.com/sass-mixin-status-indicators https://teckstack.com/sass-mixin-status-indicators#respond Sat, 02 Jul 2016 09:53:46 +0000 http://teckstack.com/?p=4937 Traffic Signal
Traffic Signal

Many times, we may need to show the status of the process in an application. Some colors speak clear enough to show the current status without saying a word. We have the great example of the traffic signal as a global indication system. The same thing applies to the web also. If we talk about any social or chat application, they must indicate the status of the users in certain way. They might use icon, colors or text. In this article, we are going to develop a status indicator for a tabular data using Sass mixin and jQuery.

The Plan

Let's assume a table having number of rows with - task title and relevant status.

HTML code

        <th>Task Title</th>
        <td>Task 1</td>
        <td><i data-status=""></i> Done</td>
        <td>Task 2</td>
        <td><i data-status=""></i> In Progress</td>

You must notice the <i> tag having attribute data-status. We are going to write Sass mixin targeting to all data-status attribute in the last <td> of each row.

jQuery Plot

Before moving to Sass code, we need to add something dynamic over HTML tags to make that Sass be considered:

$('tr').each(function() {
    var $TR = $(this),
        $TD = $TR.find('td:last-child'),
        TDText = $TD.text(),
        TDTrimmed = TDText.trim().replace(/ /g, '_').toLowerCase(),
        $status = $TD.find('i');
    $status.attr('data-status', TDTrimmed);

In above code snippet, we are grabbing the text from the last cell of each row. Also we are using pre-defined jQuery functions like trim(), toLowerCase() and replace() to achieve our goal. We ended up by setting the replaced text to data-status attribute.

$status.attr('data-status', TDTrimmed);

Pretty much simple, right?

Sass Mixin

// placeholder containing common properties 
    text-indent: -9999px;
    display: inline-block;
    width: 10px;
    height: 10px;
    vertical-align: middle;
    margin-right: 10px;

    @include borders-radius(10em);

    content: attr(data-status);

// defining mixins
@mixin borders-radius ($radius...) {
    -webkit-border-radius: $radius;    
       -moz-border-radius: $radius;
            border-radius: $radius;
@mixin status-indicator($bg: #f00 //default color) {
    @extend %indicator; // using placeholder
    background: $bg;

// ---- calling @mixin
i[data-status="done"]:before {
    @include status-indicator(lightgreen);

i[data-status="in_progress"]:before {
    @include status-indicator(orange);

In above Sass code, we first defined placeholder named %indicator having common properties required and we are going to use the same inside @mixin status-indicator. So the question is why extra placeholder? Because we can separate the code meaningfully and that makes logical separation.

Similarly, we have another @mixin borders-radius ($radius...). As the name says, it would generate border-radius and we have various browsers prefixes too. So when we use @include borders-radius(10em 5em 10em) that will compiled as below:

div {
    -webkit-border-radius: 10em 5em 10em;
       -moz-border-radius: 10em 5em 10em;
            border-radius: 10em 5em 10em;
