AngularJS - Open source JavaScript front-end framework

AngularJS has the following features and advantages:

• Two-way data binding: This means that changes in the model (data) are automatically reflected in the view, and vice versa, greatly simplifying the development process.

• Modular design: Allows applications to be broken down into manageable modules, improving the maintainability and reusability of the code.

• Directives: The behavior and appearance of HTML elements can be customized, enhancing the functionality of HTML.

• Dependency injection: Helps manage dependencies between components, making the code more testable and extensible.

AngularJS performs well in building complex single-page applications (SPAs), such as enterprise-level management systems, front-ends of e-commerce platforms, etc.

However, with the development of technology, AngularJS also has some limitations:

• Performance issues: Performance bottlenecks may occur when dealing with large applications.
• Version update: Subsequent Angular versions are quite different from AngularJS, which makes upgrade and migration difficult.

Nevertheless, AngularJS still has an important historical position in the field of front-end development, and provides valuable experience and ideas for the development of modern front-end frameworks.
