 What is the difference between AngularJS and Angular? 003

  What is the difference between AngularJS and Angular?

AngularJS and Angular share the name but are distinct frameworks with key differences:

Programming Language:

  • AngularJS: JavaScript only.

  • Angular: Primarily TypeScript (superset of JavaScript with optional static typing) offering better code clarity and error detection.


  • AngularJS: Directive-based, focused on code reusability.

  • Angular: Component-based, emphasizing modularity and clear application structure.

Data Binding:

  • AngularJS: One-way data binding by default, requiring manual updates for the model to reflect UI changes.

  • Angular: Two-way data binding by default, simplifying data management.

Other Differences:

  • Dependency Injection: More robust and preferred in Angular.

  • Mobile Support: Built-in in Angular, requires additional libraries in AngularJS.

  • Routing: Different syntax and approaches.

  • Community and Support: AngularJS is relatively mature, but Angular enjoys active development and a larger community.


Angular is a complete rewrite of AngularJS, addressing its limitations and offering a more modern, scalable, and performant framework. While AngularJS might be suitable for small projects due to its ease of use, Angular is generally preferred for large-scale, complex web applications due to its advanced features and structured approach.

Choosing between them depends on your project's requirements, team expertise, and desired level of modernity and maintainability.
