What is React? React JS Explained with Examples, Features & Advantages
What is React JS? (Complete Beginner's Guide) Introduction Traditional websites reload the entire page whenever a user clicks a link or submits a form, which can make the experience feel slow. Modern web applications solve this problem by updating only the parts of the page that change. React JS is one of the most popular JavaScript libraries used to build these modern, fast, and interactive user interfaces. It allows developers to create reusable components, efficiently update web pages, and build applications that provide a smooth user experience. Developed by Facebook (now Meta) in 2013, React is now used by thousands of companies around the world, including Instagram, Netflix, WhatsApp Web, Airbnb, and many others. Its simplicity, speed, and flexibility have made it a favourite choice for both beginners and professional developers.
