ReactJS Tutorial: Learn React from Basics to Projects

If you already know HTML, CSS, and basic JavaScript, then learning React is the next step naturally. React is the popular JavaScript library for building modern and interactive user interfaces. It is also a commonly requested skill in frontend development job listings in India.

Here is the problem React solves. In plain JavaScript, when data changes, you have to manually find the right element and update it  “document.getElementById(...)”, then “innerText = …”, again and again. A small page is fine. In a page with a cart, a search bar, a user menu, and live notifications, it becomes very hard to keep everything in sync.

React flips this around. You describe what the screen should look like for a given set of data, and React handles the updating for you.
