Introduction to React.js

1.What is React?
*React.js is a JavaScript library used to build user interfaces (UIs), especially for web applications.
*React was created by Facebook (now Meta) and is widely used for building modern, interactive websites and web applications.
*Instead of writing one large application as a single piece, React allows us to divide the UI into small, reusable parts called components.

For example, a website can have components such as:
Navbar
Header
Button
Login Form
Product Card
Footer

These components can be created once and reused wherever needed.
