To keep things organized, let's create a folder for this workshop.

Run this command to make a directory called javascripting (or something else if you like):

mkdir javascripting

Change directory into the javascripting folder:

cd javascripting

Create a file named introduction.js:

touch introduction.js

Or if you're on Windows:

type NUL > introduction.js

(type is part of the command!)

Open the file in your favorite editor, and add this text:

console.log('hello');

Save the file, then check to see if your program is correct by running this command:

javascripting verify introduction.js

By the way, throughout this tutorial, you can give the file you work with any name you like, so if you want to use something like catsAreAwesome.js file for every exercise, you can do that. Just make sure to run:

javascripting verify catsAreAwesome.js
