Angular is a full-featured framework for building web applications. It was developed and is maintained by Google, and is often used for building large-scale, complex web applications. Angular uses a more imperative approach to programming, which means that developers have more control over the implementation details of their applications. Angular also provides a set of built-in features and tools, such as a dependency injection system, a reactive programming library, and a comprehensive set of built-in services, directives, and pipes.
Both React and Angular have strong communities and are widely used in the industry. The choice between the two often comes down to personal preference and the specific requirements of a project.
