Angular is a JavaScript framework for building web applications. Developed and maintained by Google, it is widely used by developers to create complex and scalable web applications.

Angular was first released in 2010 as AngularJS, the initial version of the framework. AngularJS focused on providing a way to build dynamic web applications using declarative programming and two-way data binding. However, over time, the framework showed limitations, and its codebase became difficult to maintain.

In 2016, Google announced the release of Angular 2, a complete rewrite of AngularJS that addressed many limitations of the original framework. Angular 2 introduced numerous features, including:

  • A new component-based architecture.
  • Improved performance.
  • Support for mobile devices.

Since Angular 2, Google has released regular updates to the framework. Key versions include:

Angular 2 (2016): The first major rewrite of AngularJS, introducing a modern architecture.

Angular 4 (2017): A smaller, faster, and easier-to-use framework with Ahead-of-Time (AOT) compilation.

Angular 5 (2017): Focused on stability with features like an improved build optimizer and support for Progressive Web Apps.

Angular 6 (2018): Improved adaptability and easier updates.
