Getting Started with React

React is a powerful JavaScript library for building user interfaces. In this post, we'll explore the basics of React and how to get started with your first application.

What is React?

React is a declarative, efficient, and flexible JavaScript library for building user interfaces. It lets you compose complex UIs from small and isolated pieces of code called "components."

Setting Up Your First React App

To create a new React application, you can use Create React App:

npx create-react-app my-app
cd my-app
npm start

Components

Components are the building blocks of React applications. Here's a simple example:

function Welcome(props) {
  return <h1>Hello, {props.name}!</h1>;
}

React makes it easy to create interactive UIs and manage state effectively.
