What is AngularJS?

Updated May 15, 2026

Short answer

AngularJS is a JavaScript-based open-source front-end framework for building dynamic single-page applications.

Deep explanation

AngularJS uses the MVC/MVVM architecture to bind data between the view and model using two-way data binding. It extends HTML with directives and handles DOM manipulation declaratively.

Real-world example
