Angular is a popular open-source web application framework developed by Google. It is designed to make the development of single-page applications easier and more efficient by providing a structured approach to building user interfaces. Angular uses a component-based architecture, allowing developers to create reusable UI components that can be easily managed and tested. One of the key features of Angular is its use of TypeScript, a superset of JavaScript that adds static typing and other enhancements. This helps developers catch errors early in the development process. Angular also includes powerful tools for routing, form handling, and state management, making it a comprehensive solution for modern web development.
