Introduction to ReactJS

ReactJS’s popularity in the JavaScript community stems from its ability to build large-scale applications where the data changes repeatedly over time. At the beginning of the interview process, an interviewer expects you to discuss an introduction to ReactJS, its features, your reason for choosing it for programming, JSX and its purpose in React development, and more. So, let’s answer some introductory questions.

What is React?

React (also known as React.js or ReactJS) is an open source frontend JavaScript library that is used for building UIs, especially for single-page and mobile apps. It is used for handling the view layer of web and mobile apps.

React was created by Jordan Walke, a software engineer working for Facebook, and later maintained by the Facebook team. React was first deployed on Facebook’s newsfeed in 2011 and on Instagram in 2012.
