What is Angular

Angular is a popular open-source web application framework primarily maintained by Google and a community of developers. It's used to build dynamic, single-page web applications (SPAs) and supports the development of complex, feature-rich web applications.

Here are some key aspects of Angular:

  1. Architecture: Angular follows the MVC (Model-View-Controller) or more specifically, the MVVM (Model-View-ViewModel) architecture. This divides the application into components that manage different aspects like UI, logic, and data.
  2. Component-Based: Angular is built around the concept of components. These are self-contained, reusable modules that encapsulate HTML, CSS, and TypeScript code. They help in building and managing the user interface.
  3. Two-Way Data Binding: Angular offers two-way data binding, allowing automatic synchronization between the model (data) and the view (UI). Changes in the model are instantly reflected in the view and vice versa.
  4. Dependency Injection: Angular has a built-in dependency injection system that helps manage dependencies between different components, making the application more modular and easier to test.
  5. Directives: Angular uses directives to extend HTML with new attributes or tags. Directives can be structural (changing the DOM layout) or attribute-based (changing the behavior or appearance of DOM elements).
  6. RxJS for Reactive Programming: Angular leverages RxJS (Reactive Extensions for JavaScript) for reactive programming, enabling easier handling of asynchronous operations and events.
  7. TypeScript: Angular is primarily written in TypeScript, a superset of JavaScript that adds optional static typing. TypeScript enhances developer productivity by catching errors during development and providing better tooling support.
  8. Routing: Angular provides a powerful routing module for building single-page applications, enabling navigation between different views or components without a full page reload.

Overall, Angular provides a robust framework for building scalable, maintainable, and high-performance web applications. Its comprehensive ecosystem, strong community support, and a wide range of features make it a popular choice for developers.
