AngularJS vs React: What are the differences?

Developers describe AngularJS as "Superheroic JavaScript MVW Framework". AngularJS lets you write client-side web applications as if you had a smarter browser. It lets you use good old HTML (or HAML, Jade and friends!) as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. It automatically synchronizes data from your UI (view) with your JavaScript objects (model) through 2-way data binding. On the other hand, React is detailed as "A JavaScript library for building user interfaces". Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.

AngularJS belongs to "Javascript MVC Frameworks" category of the tech stack, while React can be primarily classified under "Javascript UI Libraries".

"Quick to develop", "Great mvc" and "Powerful" are the key factors why developers consider AngularJS; whereas "Components", "Virtual dom" and "Performance" are the primary reasons why React is favored.

AngularJS and React are both open source tools. React with 132K GitHub stars and 24.5K forks on GitHub appears to be more popular than AngularJS with 59.6K GitHub stars and 28.9K GitHub forks.

Airbnb, Uber Technologies, and Facebook are some of the popular companies that use React, whereas AngularJS is used by Google, Lyft, and Udemy. React has a broader approval, being mentioned in 3224 company stacks & 3088 developers stacks; compared to AngularJS, which is listed in 2799 company stacks and 1860 developer stacks.
