Creating React Application And Installing Module:
Step 1: Create a React application using the following command:

Step 2: After creating your project folder i.e. foldername, move to it using the following command:
cd foldername
Step 3: After creating the ReactJS application, Install the required module using the following command:

Project Structure
Example: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.
Javascript
