Top 10 Reasons to Use AngularJS Framework
In this tech-savvy world, web-based technologies like AngularJS are one of the incredible ways to build a powerful and interactive single-page site as well as web-based mobile applications on a budget.
Angular JS is an open-source JavaScript framework that integrates all necessary features. Out of all, two-way data binding is the primary function of Angular JS.
Basically, when a user interacts with an Angular JS application, the view and the model get synchronized, and the model’s logic gets updated automatically thus, the DOM also gets updated.
Therefore, if you’re a web developer, then it is of utmost importance for you to utilize cutting-edge technologies that can help you complete the project on time.

With that being said, we’ve thoroughly explained the top 10 reasons to make you understand why web developers like you should use this advanced JavaScript framework for developing your next Web application.
- Smooth MVC
Most of the available frameworks generally implement MVC by requesting you to divide your web app into MVC components, then asking you to write your app code to string them up together.
But luckily, this isn’t the case with Angular JS.
Angular implements MVC in your web app by requesting you to divide your app into MVC components and then Angular does the rest for you. This will save you quite a time.
Additionally, Angular acts as a mediator and manages app components for you.
- A Declarative User Interface
In Angular, HTML is used to define the web app’s user interface.
This means, the app interface is less fragile to reorganize and things are less likely to split. Additionally, you can bring more UI developers for your web app when the view is written in HTML. This is because HTML is a declarative language that is less convoluted and more intuitive.
Also, the special attributes in the HTML establish which controllers to use for each individual element.
- POJO Data Models
Data models in Angular JS are POJO (Plain old Javascript objects) meaning, you don’t need to use external getter and setter functions.
You can simply add and change properties directly, which will make your app code look cleaner as well as more intuitive. On top of all these, all properties found on the scope object will be bound to the view automatically by Angular.
This means, the Angular JS watches the changes and updates the view of your web app automatically.
- Customized Directives
In Angular JS, you can bring additional functionalities to HTML with customized directives.
That being said, you’ll never have to manipulate the DOM as you’ll just have to assign attributes to elements to add any out-of-the-box functionalities.
- Flexible Filters
The flexible filters in Angular JS filter the data before they reach the view and they can involve filtering an array based on a parameter and implementing pagination.
These filters are basically designed to be standalone functions that are separate from an app, but these filters are only with data transformations.
- Less Code
In Angular JS, you won’t have to write your MVC pipeline meaning, you’ll now have to write less code to get things done.
The view is defined with HTML, data models are simpler, and you don’t have to put data manually in the view as the Data-binding will take care of that.
Additionally, the flexible filters in Angular JS allow you to change the code in the view level without changing the controllers.
- Service Providers
Controllers are just simple functions that have only one job which is to manipulate scope. And unlike other frameworks, controllers don’t inherit from anything.
Now if you’re thinking that controllers are so simple, then where are you going to perform all the heavy lifting, but don’t worry Angular JS has introduced Services for that job. Services in Angular JS simply provide an outward API to help you expose whatever you want to.
However, most of the time the services sync up to your server and maintain the offline data store.
This means you can use these services to create a resource-sharing service for allowing multiple controllers to share the same resource.
- Context-Aware Communications
In case you don’t want unrelated MVC components to read your messages, then it’s possible in Angular JS.
The broadcast() function will send a message to all child controllers, whereas the emit() function will send a message to all ancestors. However, PubSub isn’t the only way to communicate with all controllers.
And as a matter of fact, if you’re only going to tell controllers to update the views, then data-binding is a better option for this job.
- DOM Manipulations
Generally, the view modifies the DOM to display data and adds behavior by manipulating the DOM. but in Angular, you’ve to put DOM manipulation code inside directives, not in the view.
This means you can now focus on the view without having to worry about JQuery calls and DOM manipulations.
- Unit Testing Ready
Angular JS uses Dependency Injection (DI) to manage your project scopes and controllers.
It is because all of the controllers in Angular depend on DI to pass the information and the unit tests in Angular JS can unsure DI for performing unit testing with mock data injection and then measure the behavior and output.
All in all, the whole is Angular is linked together by the Dependency Injection.
This is better than all traditional ways of testing web applications by developing separate test pages that invoke a single component and then interacting to see if it worked out.
Conclusion
We hope you know a better idea of why Angular is a more powerful Javascript framework with the help of the above 10 points.
In fact, the AngularJS Developers Team has recently launched Angular 2.0, which is a new & upgraded version of Angular.
In the new version, they’ve included important changes like mobile-specific routing, comprehensive routing, and internationalization which concludes that the Angular team is working hard to make it a robust and powerful JavaScript framework.
