Why Use Angular JS?

 

AngularJS is a structural framework for dynamic web apps. It lets you use HTML as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. AngularJS’s data binding and dependency injection eliminate much of the code you would otherwise have to write.

The main Angular advantages over its closest rival, KnockoutJS is that there is no need to use observable functions; Angular analyses the page DOM and builds the bindings based on the Angular-specific element attributes. That requires less writing, the code is cleaner, easier to understand and less error prone.

Seeing the growing popularity of Angular JS, we give you 7 reasons why you should also be using Angular JS.

 

1. Super User Experience

Apart from the main technical reasons stated above, Angularjs is awesome in making the app more visually appealing for the audience. Visualforce pages are created to make the UI terrific and accomplish the objective of making the application aesthetically more appealing. To make the task simple, prebuilt libraries, components and modules are present in the framework that speeds the development time and alongside gives the app a visual bonus as well.

2. Full UI Support

To describe an application’s UI, Angular takes into use HTML which is a declarative programming language. HTML creates a less complicated and more intuitive user interface that is solid unlike other interfaces written in JavaScript. Also, HTML allows you to declare which controllers should be employed for specific UI element so that you can focus more on the look and feel of your app’s UI. Just mention what you want and Angular will take the dependencies in control.

3. Simple Testing

There are certain parts of the application present in Angularjs modules that can be easily be manipulated. With the help of module separation, you are comforted by loading only necessary services and thus smoothly conduct automatic testing. Further, if you stick to ‘one file, one module’ pattern, you don’t have to worry about keeping module loading order to memory.

4. Improved Flexibility

Just like directives, filters are standalone functions that distill the data before it reaches the view. These differ from your app and deal in activities like implementing pagination, formatting decimal places on a number and reversing a text string. The filters can be utilized in controllers, services, templates and even directives. These enhance flexibility tremendously and are so resourceful that you can tackle a HTML table without any JavaScript.

5. Backed By Google

As Angularjs has a strong backing of Google, the developers are relieved to be working with a solid code base that will offer complete support to the project. Being an exception to the other common JavaScript application frameworks, which are created by independent hobbyists, Angular is the result of brilliant work by genius Google engineers Adam Abrons and Misko Hevery. This is one of the major reasons why developers use Angular over other JavaScript frameworks like Ember.JS and Knockout.JS.

6. Less Coding

 

Coders need to spend less time in coding process as AngularJS requires less coding. Without a doubt it is a great deal for developers.

A glance where it asks for fewer codes:

• AngularJS developers community do not require to write their own pipeline

• Its data model is simple and you do not need any getter/setter functions

• Its data-binding feature grants developers to stop giving data manually into the view

• AngularJS is defined using HTML for view to make it more specific

• As directives are separate from app code, other teams can write it without any integration issue.

• Filters allow developer to manipulate the data on the view level without changing any of your controllers

• AngularJS has a built-in dependency injection subsystem useful for developers for creating applications in an easier style including testing process as well.

7. AngularJS Handles Dependencies

Dependency injection is something Angular does quite well. I’ll admit I was skeptical we even needed something like that on the client, but I was used to the key scenario being the dynamic loading of modules. Oh, wait – what did you say? That’s right, with libraries like RequireJS you can dynamically load JavaScript if and when you need it. Where dependency injection really shines, however, is two scenarios: testing and Single Page Applications.

For testing, Angular allows you to divide your app into logical modules that can have dependencies on each other but are initialized separately. This lets you take a very tactical approach to your tests by bringing in only the modules you are interested in. Then, because dependencies are injected, you can take an existing service like Angular’s $HTTP service and swap it out with the $httpBackend mock for testing. This enables true unit testing that doesn’t rely on services to be stood up or browser UI to render, while also embracing the ability to create end-to-end tests as well.
