A Simple App | React JS Tutorial for Beginners – Part 1

Welcome to the first part of our React JS tutorial for beginners series. In this tutorial, we will be building a simple app using React JS. If you’re new to React JS, don’t worry – we’ll guide you through the basics and help you get started with this popular JavaScript library.

What is React JS?

React is a JavaScript library for building user interfaces. It was developed by Facebook and is used to create interactive and dynamic web applications. React uses a component-based architecture, which means that you can easily create reusable and encapsulated UI components.

Setting Up Your Development Environment

Before we start building our app, you’ll need to set up your development environment. You’ll need to have Node.js and npm (Node Package Manager) installed on your computer. Once you have Node.js and npm installed, you can use npm to install the create-react-app package, which will help you set up a new React project.

Creating Your First React App

Once your development environment is set up, you can use the create-react-app package to create a new React project. Open your terminal or command prompt and run the following command:

        npx create-react-app simple-react-app
    

This command will create a new directory called simple-react-app and set up a new React project inside it. Once the project is created, you can navigate to the project directory and start the development server by running:

        cd simple-react-app
npm start
    

After running npm start, a new browser window should open, and you should see the default React app running. You’re now ready to start building your own app using React JS!
