Angular JS Key Features

Even though Angular (Angular 2+) has now largely succeeded AngularJS, it still had many key features that made it popular.

There are some key feature of it as follow,

Two-way data binding- This feature allowed the automation of data transfer between the model and the view. Changes made to the model would be immediately reflected in the view and vice versa, without the need for explicit DOM modification.

Directions- Directives in AngularJS extend HTML to include new properties and allow the creation of custom HTML tags that act as reusable objects. Examples include ng-repeat, ng-show, and ng-hide.

MVC (Model-View-Controller) Architecture- AngularJS followed the MVC design pattern, where the model contained the application data, the views displayed the data, and the controllers handled the logic between the model and the view

Dependency Injection (DI)- AngularJS had a built-in dependency injection subsystem that helped developers manage dependencies and promote modularity in their applications

Templates- AngularJS used HTML templates with additional markup (guidelines) to bind data efficiently. Templates can be listed directly in HTML files or loaded asymmetrically via $templateCache or HTTP.

Routing- AngularJS provides client-side routing through the ngRoute module, allowing developers to create single-page applications (SPA) with multiple views and move between them without reloading the entire page.

Testing- AngularJS was designed with testability in mind. It provided support for unit testing and end-to-end testing and made it easier to write and run tests for AngularJS applications.

Filters- Filters allow data formatting to be applied to the template. These can be used to edit numbers, dates, and currencies directly in the view.

Localization- AngularJS provides tools for creating multilingual applications, allowing developers to create templates with international content.

All these features together make AngularJS a powerful framework for building dynamic and functional web applications.
