React JS

React is a free and open-source front-end JavaScript library for building user interfaces based on UI components. It is maintained by Meta and a community of individual developers and companies. React JS is a JavaScript library used in web development to build interactive elements on websites.

Is ReactJS frontend or backend?

ReactJS is an open-source, component-based front-end library responsible only for the view layer of the application. It is maintained by Facebook. To get an overview of what React is, you can write React code directly in HTML. But in order to use React in production, you need npm and Node. js installed. MongoDB is the best database for ReactJS.

Why JavaScript vs React?

Unlike pure JavaScript, apps in React are not created as one long stretch of a file but as small building blocks called Components. These components are fundamental to React apps. Your entire website is divided into these small components which when put together complete the UI of the website.

What is ReactJS vs Angular?

Angular is a Javascript framework built using Typescript, while Reactjs is a Javascript library and built using JSX. Angular is mostly used to build complex enterprise-grade apps like single-page apps and progressive web apps, while React is used to build UI components in any app with frequently variable data.

What are the advantages of ReactJS?
  • Makes JavaScript coding easier.
  • Extremely competent.
  • Excellent cross-platform support.
  • Handles dependencies.
  • Template designing made easy.
  • Provides amazing developer tools.
  • UI-focused designs.
  • Easy to adopt.

React helps you work smarter, not harder, by allowing you to re-use components you’ve already written across the same application and on totally different builds with similar functionality. Reusable components also help to maintain a consistent code style and the overall maintainability of the application.
