Now we will go through and understand the purpose of each generated file/folder.

Once the installation is over you can see the app ‘myfirst-app’ get created with a bunch of files like node modules, public, src, and readme.md etc., inside the folder.

Also, it installs a bunch of dependencies like react, react-dom, react script, and some other packages too.

Once you enter the command in a terminal, it will install React for us, after that it will create the app ‘my first app.

To create our react app using this package, by using the below command.

After specifying the ‘ npx create-react-app command, we need to provide the name of our react application.

And in this command, what npx do is, install the Create react app for us, and also it creates react application for us as well.

In the below command, the npx is npm package runner, which is get installed when we install the Node js.

That means we don’t need to install and set up the React in the local machine, instead this package will do all that for us. Once we install the package it will automatically create a React app for us.

In order to create a react app, we are going to use of package called ‘Create react-app’.
