AngularJS is an open-source JavaScript framework developed by Google. It is designed to make front-end web development easier by providing a structured way to build dynamic single-page applications (SPAs). AngularJS extends HTML with additional attributes and binds data to HTML with expressive, easy-to-understand syntax.
Here are some key features of AngularJS:
- Two-Way Data Binding: Automatically synchronizes data between the model (JavaScript objects) and the view (HTML).
- MVC Architecture: Implements the Model-View-Controller design pattern, which helps in separating concerns within an application.
- Directives: Special HTML attributes that enable custom and reusable DOM elements and behaviors.
- Dependency Injection: Facilitates the development and testing of applications by injecting dependencies rather than hard-coding them within components.
- Templates: Uses HTML templates to render the view, which are compiled in the browser and into the DOM.
- Testing: Provides support for both unit and end-to-end testing.
AngularJS was a significant advancement in web development when it was first released, but it has since been succeeded by Angular (also known as Angular 2+), a complete rewrite of AngularJS that offers improved performance, a more modular architecture, and better support for modern web standards.
