React
React is a JavaScript library for building user interfaces.React is used to build single-page applications.React allows us to create reusable UI components.
Components
React components are independent, reusable building blocks that define what gets displayed on the user interface in a React application. They serve a similar purpose to JavaScript functions but are specifically designed for rendering UI elements.
Virtual DOM
The React Virtual DOM (Document Object Model) is a lightweight, in-memory representation of the actual DOM. It is a key concept that enables React's efficient UI updates and performance.
