React helps to build interactive websites more easily. Without React, making websites that can update and render efficiently would be quite difficult and more complex.
What is it?
React is a library that helps you build Single Page Applications (SPAs).
It allows you to build websites that can update parts of the page without needing to refresh the entire page.
How is it used?
Components: You build small parts called components (like buttons or forms) that you can use over and over again in your website.
JSX: It's a special language that lets you write components that look like HTML (the language of the web).
State \& Props: These are ways to store information. State is for information that can change, and props is for information that is passed from one component to another.
Lifecycle Methods: These are special functions that run at specific times. For example, when a component is first put on the screen, or removed from the screen.
Virtual DOM: React uses a smart way to update the website quickly. It keeps a copy of the website and only updates the parts of the real website that need to change.
