Introduction to React.js

In the React.js introduction module, we will start by understanding what this library is. React.js is a JavaScript library used to build dynamic and interactive user interfaces (UI). For example, imagine you are creating an e-commerce website.

With React.js, you can divide the interface into reusable components, such as a header, shopping cart, and product list. This makes the code more organized and easier to maintain.

Additionally, React.js uses the concept of Virtual DOM to update only the parts of the page that have been modified, making the application faster and more efficient.

This module is the first step in understanding how React.js can transform the way you develop web applications.
