First, create the directory where you will write your code. It needs to contain a [package.json](https://docs.npmjs.com/getting-started/using-a-package.json) file
for npm to know in which folder to install the subsequent packages - `npm init` does this for us.
You can change `learnyoureact` to any name you like.

`$ mkdir learnyoureact; cd learnyoureact; npm init -y;`
