Welcome to Let’s React!

Are you ready to dive into the world of React? In this article, we will provide you with an introduction to React and guide you through creating your first React app. Let’s get started!

What is React?

React is a JavaScript library for building user interfaces. It was developed by Facebook and is widely used by developers to build dynamic and interactive web applications. React allows you to create reusable components and efficiently update the user interface when data changes.

Getting Started with Your First React App

1. First, make sure you have Node.js and npm installed on your computer. You can download them from here.
2. Next, open your terminal and create a new directory for your React app.
3. Run the following command to create a new React app using Create React App:
   npx create-react-app my-first-react-app
4. Once the app is created, navigate to the newly created directory:
   cd my-first-react-app
5. Start the development server by running:
   npm start
6. Open your browser and go to http://localhost:3000/ to see your React app in action!

Understanding Your First React App

Congratulations! You have successfully created your first React app. Now, let’s take a closer look at the files and structure of your app:

• src/index.js: This is the entry point of your app where React is rendered onto the DOM.
• src/App.js: This is the main component of your app where you can start building your UI.
• public/index.html: This is the HTML file where your app is injected into.
