2 Why Learn Angular?

Angular is a robust framework maintained by Google.

Angular is well-suited for building Single Page

Applications (SPAs).

Angular follows a component-based architecture, making it easier to manage and reuse code.

Angular is built with TypeScript, that adds static typing to enhance code quality. you can build applications for various platforms, including web, mobile, and desktop
