AngularJS is a JavaScript-based web framework developed by Google for building single-page applications (SPAs). It extends HTML with new attributes and binds data to HTML with expressions. AngularJS simplifies the development and testing of applications by providing a framework for client-side model–view–controller (MVC) and model–view–viewmodel (MVVM) architectures.

Key Features

Directives

Directives are special tokens in the markup that tell the library to do something to a DOM element (e.g., hide it, show it, or repeat it). Some commonly used directives include:

• ng-app: Declares the root element of an AngularJS application.

• ng-model: Binds the value of HTML controls (input, select, textarea) to application data.

• ng-bind: Binds the innerHTML of an HTML element to application data.

• ng-repeat: Instantiates a template once per item from a collection.
