Why AngularJS Continues to Lead: Key Features, Benefits, & Solutions for Modern Development in 2025

For years, the tech world has debated the fate of AngularJS, Google’s original JavaScript framework, especially after the release of Angular (2+) in 2016. The shift to a more robust, TypeScript-based Angular left many wondering: 

"Are AngularJS Development Services dead? And what about Angular itself—is it still a viable choice in 2025?"

Even eight years since Angular's major update, Angular JS is thriving with over 58k stars on GitHub and a growing community.

Yes, AngularJS is no longer actively maintained, and frameworks like React and Vue have gained attention for their speed and flexibility. But Angular, the framework that rose from the legacy of AngularJS, is far from irrelevant.

What is AngularJS?

AngularJS, launched by Google in 2010, quickly became a major force in web development. It was created to simplify the development of single-page applications (SPAs) and dynamic websites. AngularJS helped developers to work with a more organized and efficient framework, making it easier to build robust, interactive web applications.

Its most notable feature was two-way data binding, which automatically synced the data between the model and the view, reducing the need for manual updates. 

AngularJS also introduced dependency injection, directives, and filters—tools that allowed developers to write cleaner, more reusable code.

However, in 2021, Google officially ended long-term support for AngularJS.

This meant no more updates, security patches, or new features. While this didn’t make AngularJS obsolete overnight, it marked a clear shift toward modern frameworks like Angular (2+) and others that were better equipped to handle the evolving demands of web development.

Here’s a simple comparison between AngularJS and Angular (2+):
