JSX: JSX is a JavaScript syntax extension. It is utilized with React to specify how the user interface ought to seem. We can write HTML structures in the same JavaScript code file using JSX. Components: Any React application is built from components, and a single app often comprises of several components.

Components are the building blocks of a React application’s UI. These components split up the entire UI into small independent and reusable pieces. Then it renders each of these components independent of each other without affecting the rest of the UI.

Note- Props are read-only.
