React and Angular

React, also called React.js or Reactjs, is a JavaScript library, and you can build user interfaces using it. Your development team can design simple views for each state of your application using React. React has components whose logic is written in JavaScript, and React updates and renders the right components when the data changes.

Angular is an open-source front-end framework based on TypeScript, and it was rewritten from AngularJS, the JavaScript-based web framework.

With AngularJS, you can develop apps that utilize the Model View Controller (MVC) architectural pattern, i.e., the data model, presentation information, and control information of the application are separate. AngularJS also supports the Model-View-ViewModel (MVVM) architectural pattern, in which there is a separation between the UI control and business logic.
