How does React.js work?

React works by breaking down a user interface into reusable components. A component is a piece of code that can be modified or updated without affecting the rest of the application.

To create a page with React, you must call each component, basically a JavaScript Function, in a specific order so that users can see it.

React also uses a virtual DOM, which is a lightweight copy of the actual DOM. It allows users to have faster upgrades and better performance.

When a change is made to the UI, React compares the virtual DOM with the actual DOM and updates the necessary components for efficient rendering.
