  • A separate option to create a pure JavaScript template
  • Virtual DOM that updates changed parts or those requiring updates
  • Small API and hence a softer learning curve – preferred by beginners

Now when do you use ReactJS?

You need a frontend UI that requires high user interaction.

  • Build a website, web app, VR application, or a mobile app
  • When the project requirements are complex
  • When you have many changes to make to a website. React can help you start by changing a few elements before moving the entire site to React.

You may use AngularJS while building video streaming applications, social applications, weather applications, travel applications, user-review applications, and eCommerce apps.

What is VueJS? | Why and When to Use VueJS?
