What are the features of AngularJS?

AngularJS, the predecessor to Angular (2+), introduced several key features that helped revolutionize web development: 1. **Two-Way Data Binding**: Changes to the model automatically update the view, and changes to the view automatically update the model. This reduces the need for manual DOM manipulation. 2. **MVC Architecture**: AngularJS uses a Model-View-Controller (MVC) architecture, helping separate concerns in the application and making it easier to manage. 3. **Directives**: AngularJS introduces directives, which are special markers on elements (like `ng-if`, `ng-repeat`) that extend HTML’s functionality, creating custom behavior and reusable components. 4. **Dependency Injection (DI)**: AngularJS uses dependency injection to manage services and components, making it easier to develop, test, and maintain applications. 5. **Templates**: AngularJS uses HTML templates to dynamically generate the view based on the data model, allowing developers to create complex UIs in a more declarative way. 6. **Filters**: Filters allow data to be transformed before it is displayed to the user, such as formatting numbers, dates, or text. 7. **Routing**: AngularJS provides an integrated routing mechanism that helps in developing Single Page Applications (SPA), allowing for easy navigation between views without reloading the entire page. 8. **Testing Support**: AngularJS is built with testing in mind. It has built-in support for unit testing and end-to-end testing using tools like Jasmine and Karma. 9. **Cross-Browser Compatibility**: AngularJS is designed to work seamlessly across all major browsers, ensuring consistent behavior for users.
