React JS is a framework that helps you build responsive web applications. Its architecture consists of components that are composed of functions and properties. Data flows from the parent component to its child components, and the top level component is known as the “App”. The key feature of React is the concept of state. A state is an object that contains observable properties and that changes as the user interacts with your interface.

React is one of the most popular libraries and frameworks, with more than 80,000 developers trusting it. This growing community makes it a strong and stable library that is unlikely to fade away anytime soon. It is an open-source library, and its community is active. Despite its growing popularity, it is still early to say whether React will be the next big thing in web development.

For instance, Uber Eats is an example of a project that uses React. The company needed to create a mobile application that would bring together clients, drivers, and restaurants. This was not a straightforward task (more information). Ultimately, the developers chose React Native because it was a framework that allowed them to share a single codebase and automatically reload code.

React was created in 2011 by Facebook developers. The aim of the project was to make it easier to maintain code. The documentation of the framework is excellent, and it is expected to become the most popular web framework by 2022. It is built on the HTML standard, which is a language for web pages. The browsers use a Document Object Model, which views a web page as a tree of nodes. The nodes represent the various HTML elements.
