🤌 React JS is an open-source Javascript library created and maintained by Facebook. It is designed to allow for the creation of large and complex user interfaces, and is highly efficient in managing updates to the page. React is popular among web developers as it allows for the creation of reusable components that can be easily integrated into different parts of a website. The use of a virtual DOM (Document Object Model) allows React to only update the parts of a page that have changed which makes it one of the fastest front-end libraries available.
🤌 React also allows for the use of JSX, a syntax extension that allows for the mixing of Javascript and HTML to create React components. This allows developers to write more concise and easier to read code, as well as more efficient use of time when building user interfaces. JSX is transpiled by Babel, a Javascript compiler that converts modern syntax into backwards-compatible code, making React available in all modern browsers.
