Implements MVC Pattern Differently
Model-view-controllers enable developers to simplify development of large web applications by keeping their user interface and business logic separated. But AngularJS implements MVC pattern in a distinct way. The AngularJS team calls the distinct implementation of MVC pattern as model-view-whatever. The model-view-whatever architecture makes it easier for programmers to improve the performance and maintainability of complex web applications.
Supports Two Way Data Binding
In addition to implementing MVC architecture differently, AngularJS also supports two-way data binding. The feature helps developers to synchronize the data between model and view components without putting extra effort. AngularJS automatically updates the web application’s frontend each time its backend changes. As AngularJS synchronizes the model and view automatically, the developers are not required to implement DOM manipulation.
Improves Server Communication
AngularJS reduces web server load significantly by supporting caching. At the same time, the built-in services provided by AngularJS help developers to improve client-server communication. The services further make it easier for web developers to work with various backend systems and solutions. Also, the developers can take advantage of the built-in services to make the data return asynchronously without writing complex code.
Implements Client-Side Form Validation
The web developers can create a variety of forms by combining HTML, CSS and AngularJS. AngularJS further helps developers to implement client-side form validation. It monitors the state of the form as well as individual text fields. It even notifies users about the current state of the form or input fields. The developers can easily validate the form input using standard HTML5 attributes. AngularJS even allow them to write and use custom validation functions.
Keeps the Code Maintainable and Testable
Provides a Built-in Dependency Injection Subsystem
Often frontend web developers use dependency injection tools to inject dependency to an object in the most appropriate way and make the objects exchange dependencies seamlessly. AngularJS simplifies dependency injection by providing a built-in dependency injection subsystem. The dependency injection subsystem makes it easier for developers to replace individual components off the web application, along with performing testing.
