What is React.js?

The React.js framework is an open-source JavaScript framework and library developed by Facebook. It’s used for building interactive user interfaces and web applications quickly and efficiently with significantly less code than you would with vanilla JavaScript.

you develop your applications by creating reusable components that you can think of as independent Lego blocks. These components are individual pieces of a final interface, which, when assembled, form the application’s entire user interface.

React.js encourages developers to separate these complex UIs into individual reusable components that form the building blocks of the whole UI. In doing so, the ReactJS framework combines the speed and efficiency of JavaScript with a more efficient method of manipulating the DOM to render web pages faster and create highly dynamic and responsive web applications

How to Use React.js

In contrast to other frameworks like Angular, React doesn’t enforce strict rules for code conventions or file organization. This means developers and teams are free to set conventions that suit them best and implement  however they see fit. With you can use as much or as little as you need due to its flexibility.

you can create a single button, a few pieces of an interface, or your entire app’s user interface.
