What are React Components?
React Components are the building block of React Application. They are the reusable code blocks containing logics and and UI elements. They have the same purpose as JavaScript functions and return HTML. Components make the task of building UI much easier.
A UI is broken down into multiple individual pieces called components. You can work on components independently and then merge them all into a parent component which will be your final UI.
Components promote efficiency and scalability in web development by allowing developers to compose, combine, and customize them as needed.
You can see in the below image we have broken down the UI of w3wiki’s homepage into individual components.
Components in React return a piece of JSX code that tells what should be rendered on the screen.
React Components
Components in React serve as independent and reusable code blocks for UI elements. They represent different parts of a web page and contain both structure and behavior. They are similar to JavaScript functions and make creating and managing complex user interfaces easier by breaking them down into smaller, reusable pieces.
