Basically, when a user interacts with an Angular JS application, the view and the model gets 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 the cutting edge technologies that can help you complete the project on time.
- #1: Smooth MVC
Most of the available frameworks generally implement MVC by requesting you to divide your web app into MVC components, then asks 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 the 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.
- #2: 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 which is less convoluted and more intuitive. Also, the special attributes in the HTML establish which controllers to use for each individual elements.
- #3: POJO Data Models
On top of all these, all properties found on the scope object will be bound to the view automatically by the Angular. This means, the Angular JS watches the changes and updates the view of your web app automatically.
- #4: 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.
- #5: Flexible Filters
The flexible filters in Angular JS filters the data before they reach the view and they can involve filtering of an array based on a parameter and implement pagination.
These filters are basically designed to be standalone functions which are separate from app, but these filters are only with data transformations.
- #6: 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 allows you to change the code in view level without changing the controllers.
- #7: Service Providers
Controllers are just simple functions that have only one job that 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 heavy lifting, but don’t worry Angular JS has introduced Services for that job.
Services in Angular JS simply provides an outward API to help you expose whatever you want to. However, most of the times the services sync up to your server and maintains 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.
- #8: Context Aware Communications
In case if 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, where the emit() function will send a message to all ancestors.
However, PubSub isn’t the only to 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.
- #9: 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.
- #10: Unit Testing Ready
The Angular JS uses Dependency Injection (DI) to manage your project scopes and controllers. It is because all of the controllers in Angular depends on DI to pass the information and the unit tests in Angular JS can unsurp 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 for testing web applications by developing separate test pages that invoke single component then interacting to see if it worked out.
