AngularJS: What and Why

Java is one of the most popular programming languages for improving web applications. From smart-phones to gaming consoles, many applications use JavaScript to enhance the user experience. JavaScript is the most popular and flexible language for web-page development. Billions of devices across the globe use JavaScript in one way or the other. If you haven’t tried AngularJS yet, you are not utilizing the full potential of Java for your eCommerce website.


What is AngularJS?

AngularJS is a client-side JavaScript MVC framework to develop a dynamic web application. AngularJS was originally started as a project in Google but now, it is an open-source framework. It is entirely based on HTML and JavaScript, so there is no need to learn another syntax or language. It is a highly preferred framework, due to its effectiveness, simplicity, and flexibility.


One of the main reasons for the popularity of Angular JS is that it lets you use HTML as a template language. While HTML is a great declarative language for documents, it is not very efficient for applications. AngularJS extends the capability of HTML by allowing you to modify different elements of your web-page.


What Makes AngularJS Different?

Static documents and dynamic applications require different approaches. The mismatch between HTML and different application development frameworks can be frustrating for programmers. AngularJS solves this issue by data binding and code reuse. In simpler words, AngularJS teaches your browser new syntax through directives.

Another main reason for the popularity of AngularJS is the fact that it presents a higher level of abstraction to the developers. It is, therefore, no surprise that AngularJS continues to be in the list of most popular JavaScript frameworks by many web development firms.


Advantages of AngularJS

  1. Open-source JavaScript MVC framework.
  2. Supported by Google
  3. No need to learn another scripting language. It’s just pure JavaScript and HTML.
  4. Supports separation of concerns by using the MVC design pattern.
  5. Built-in attributes (directives) makes HTML dynamic.
  6. Easy to extend and customize.
  7. Supports Single Page Application.
  8. Uses Dependency Injection.
  9. Easy to Unit test.
  10. REST friendly.


Why Should you Use AngularJS?

As you might have got an idea by now, AngularJS is simplified elegance in the front-end development. Let’s explore some of the features that give AngularJS an edge over other alternatives:


1. Efficient usage of MVC

In numerous frameworks require the developer to split the application into MVC components. The developer has to further write a code to join them up. MVC in Angular can be implemented easily and efficiently as it only requires the user to split the application into MVC components. Angular manages and takes care of the rest by serving as a pipeline that connects them.


2. Data Binding

AngularJS uses a two-way data binding for synchronization of data automatically. As a result, the architecture’s view layer is a replica of the model layer. Since the view and model layers are updated continuously, they are always in sync with each other. Any changes made in the view layer are automatically reflected in the model layer and vice versa.

3. Dependency Injection

A built-in dependency injection subsystem is present in AngularJS. Dependency Injection can be defined as a software design pattern that deals with how the components get hold of their dependencies. The AngularJS injector subsystem assists the developer in creating components, resolving their dependencies and providing them to the other components as requested.


4. Lesser Code

Since we don’t need to write the code for the MVC pipeline, the length and the complexity of our code decreases. Additionally, we define the view by using HTML, which proves to be concise. We also use data binding, which simply means that we do not have to put the data into the view manually. Filters, on the other hand, allow the user to manipulate data on the view level without changing the controllers.

5. Code Reusability

AngularJS allows HTML grouping to reuse its components. The developers can reuse the identical code developed already. Code-reusability saves time and results in faster development while ensuring uniformity of similar web applications.


6. High Performance

Robust features such as Filters, Animations, Form Validation, API Client and Routing make AngularJS a powerful framework. These features enhance web development and make it efficient and simple.

7. Filters

Filtering in the AngularJS framework is used to manipulate data before it reaches the top layer of the application. Filtering in AngularJS can be implemented simply by creating a subset of an array to filter out unnecessary information. Additionally, you can perform complex data transformations like pagination by modifying different parameters of your code. AngularJS ensures that information is in proper format before presenting it to the user.

8. Templates

Different templates are available in AngularJS to develop your code quickly. You can extend the functionalities of plain HTML templates by adding instructions. This feature gives you an idea about how the model looks in the end view.


AngularJS automatically offers everything you require to build a Create, Read, Update, Delete (CRUD) application. All leading eCommerce website development services follow CRUD algorithm. Several out-of-the-box features like data binding, dependency injection, code-reusability, etc. provide quick development. The feature-rich AngularJS allows you to develop user-friendly web applications. It automatically handles the cross-border compatibility and is easy to implement. These unique features of AngularJS provide many compelling reasons to use AngularJS framework for professional development.
