Getting Started with React

React is a powerful JavaScript library for building user interfaces. In this article, we'll explore the key concepts that every React developer should understand.

What is React?

React is a JavaScript library maintained by Facebook that simplifies the process of building interactive user interfaces. It uses a component-based architecture to create reusable and maintainable code.

Key Concepts

Components

Components are the building blocks of any React application. They are reusable pieces of UI that encapsulate their own structure and behavior.

JSX

JSX is a syntax extension that looks similar to HTML. It allows you to write UI code in a more readable and intuitive way.

Props

Props are the way to pass data from parent to child components. They are read-only and help maintain unidirectional data flow.

State

State allows components to manage their own data. Unlike props, state is mutable and can be updated over time.
