Angular.js, often referred to as Angular, is a popular JavaScript-based open-source front-end web application framework. It is maintained by Google and is widely used to build dynamic and interactive web applications.
Angular.js extends HTML with new attributes and directives, making it more expressive and powerful for building complex and interactive user interfaces. It follows the Model-View-Controller (MVC) architectural pattern, which helps in organizing and structuring web applications.
With Angular.js, developers can create reusable components, handle data binding between components and views, and easily manage application state. It also provides features like dependency injection, form validation, routing, and animation, which further enhance the development experience.
