Five Reasons Why a Web Developer Should learn AngularJS

AngularJS is the most popular framework which has outshined every other JavaScript framework. With some of the amazing features like less coding, effective and time-saving, Angular has emerged as one of the popular technology in the world of web development. Certainly, it has made the life of JavaScript developers much easier. Angular is now being used on over 9,000 websites, including some famous companies like Intel, Sprint, NBC, Walgreens and ABC News. The statistic shows the popularity of Angular framework among the developers. AngularJS is one of the JavaScript frameworks, which allows the usage of HTML as a master language. Let’s see why it is worth for a web developer to start learning AngularJS. Why AngularJS? 1. AngularJS supports Single Page Applications Single Page Applications (SPA) has now gained popularity because nobody likes to wait too long for a website or application to load. From a design perspective, SPAs are far more responsive and these applications are able to pull up the same kind of experience as native apps on the web. Single-page apps load existing HTML pages in the browser and update the contents dynamically as per the user input. This enhances the user experience and performance of the website or app. Since the entire rendering happens on the client side, it reduces the server network traffic. These benefits make it more interesting for developers to work on creating the seamless user experience and fluid interactions. 2. AngularJS enables design development workflow AngularJS helps designers add HTML in the applications while designing without breaking an application. As it depends on certain id or structure to locate an element and perform tasks. Designers can escape the job of rearranging the codes, they can rather move elements around the code. 3. Angular handles dependencies effectively By virtue of its built-in dependency injection subsystem, AngularJS makes the process of unit testing much easier. Developers are only required to add dependencies as a parameter rather than searching for it. AngularJS make things easier for developers and offers dependencies instantly. In the case of SPAs, developers can add dependencies and dynamic loading without worrying about namespace and spin up an instance. 4. AngularJS supports parallel development AngularJS has made the entire development process very easy for developers. Earlier web developers had to depend on each other, but this not the case with AngularJS. With the support of JavaScript, patterns can be used, which makes it modular. This doesn’t mean that AngularJS completely removes dependencies. However, it makes it easy to manage them. Considering a scenario, for an application if huge force is employed to work on the various key operations, AngularJS breaks down several actions into its sub-controllers and services. This helps developers to test the code separately without damaging other’s work. 5. Behavior with directives With directives, AngularJS provides more functionality to HTML as it contains various elements such as lightbox, grid, accordion, etc. These help developers to use them without manipulating the DOM. The directives can be used directly by just allocating attributes to these elements. Developers can generate their own HTML elements with the help of directives in AngularJS. Adding DOM manipulation code into directives will isolate them from the MVC applications. This makes the MVC applications to only update the view with new information.

AngularJS is one of the JavaScript frameworks, which allows the usage of HTML as a master language. Let’s see why it is worth for a web developer to start learning AngularJS.

Why AngularJS?
