Advantages of AngularJS
- Two-way Binding Of Data:
Angular JS allows you to do two-way data binding that enables view and model to coordinate with the changes in one another.
The MVC or Model-View-Controller pattern means a lot of different things to different people. AngularJS does not implement MVC in the traditional sense, but rather something closer to MVVM (Model-View-ViewModel).
- Dependency Injection:
AngularJS has a built-in dependency injection subsystem that helps the developer by making the application easier to develop, understand, and test. Dependency Injection (DI) allows you to ask for your dependencies, rather than having to go look for them or make them yourself. Think of it as a way of saying “Hey I need X’, and the DI is responsible for creating and providing it for you.
- Service Providers:
AngularJS introduces the “Service” to perform some light lifting inside the controller so that the main focus of the controller remains on the view update and the scope. The service provides the exposure to the API to expose what we want and need to expose. It does not deal with the MVC of the application. It also communicates with the servers if required to monitor the data flow and also perform some push and pull methods to take out data and send data to the server. A resource-sharing service is provided to the controllers to share their resources.
Filters work is to just filter the data before it reaches the view. It performs the paginations and also filters a data array to the parameters. The functions are modified according to the ideal parameters but these are only data transformation tasks done. It works with regards to putting the data in the proper format before it is placed in the view. For example, putting a decimal point in several reversing the order of numbers/serial in the desired range.
The dependency injection in AngularJS allows you to declaratively describe how your application is wired. This means that your application needs no main() method which is usually an unmaintainable mess. Dependency injection is also a core to AngularJS. This means that any component which does not fit your needs can easily be replaced.
AngularJS was designed from the ground up to be testable. It encourages behavior-view separation, comes pre-bundled with mocks, and takes full advantage of dependency injection. It also comes with an end-to-end scenario runner which eliminates test flakiness by understanding the inner workings of AngularJS.
- Deep Linking:
A deep link reflects where the user is in the app. This is useful so users can bookmark and email links to locations within the app. Round trip apps get this automatically, but AJAX apps by their nature do not. AngularJS combines the benefits of deep linking with desktop app-like behavior.
AngularJS offers developers many ways to accomplish functionalities in a simple, efficient, and testable manner. The overall point of AngularJS is one framework that is used for mobile and desktop applications.
