  • Components- React consists of multiple components and each one has its logic and controls. These components are reusable and help in maintaining the code when working on large-scale projects.
  • One Way Data Binding- React follows a unidirectional flow of data and allows developers to use the callback feature to edit components. It provides developers with more control over the app and makes it more flexible and effective.
  • Virtual DOM- It is the virtual representation of DOM. Whenever the app is modified, the entire UI is rendered again by the virtual DOM, by updating the components that have been modified.

  • Developer Toolset- React Developer Tools is a browser extension. It allows developers to observe reactive component hierarchies, discover child and parent components, and inspect their current state and props.
  • Easy to Learn- It doesn’t impose any patterns, templates, complex internals, or architecture like MVVM or MVC. Once you get familiar with components’ states, props, and life cycles, react is very easy for you.
  • Strong Community- React JS is currently being supported by Facebook and Instagram engineering teams, plus external experts. This strong community of developers allows you to find issues for your problems easily.
