React JS is a new framework for building web applications. Unlike the predecessors, which rely on vanilla JavaScript, React is much more focused on user interfaces. This means that it’s fast and reliable. It was developed by a Facebook engineer, Jordan Walke. Here’s a look at how the framework works.

The architecture of React is very flexible. It doesn’t require the entire page to be reloaded because the libraries only render the parts of the page that need to change. Instead of creating a static DOM, React uses a virtual DOM that only reloads when an object’s data state changes.

The virtual DOM keeps track of the elements a user interacts with. This ensures that the DOM is updated only when they are relevant, which improves performance. Traditionally, you’d have to reload your website every time you changed the content on your website. But React uses a Virtual DOM to improve the user experience.

For beginners, you can check out the YouTube React Crash Course for Beginners 2021, an updated course that covers the basics of React. This video tutorial walks you through the basics and builds up to a finished project. For more advanced users, you can check out BestofReactjs, a site where you can browse pre-made components from developers worldwide (more information). Another useful website is brillout, which compiles interesting React libraries and components.

React JS is a JavaScript library that helps you develop web applications. It is similar to a framework but has many advantages over other popular frameworks. It is the ideal framework for web applications.
