Intro to JavaScript Functions Setup

Open your Terminal application and navigate to your ~/code/ga/lectures directory:

cd ~/code/ga/lectures

Make a new directory called intro-to-javascript-functions, then enter this directory:

mkdir intro-to-javascript-functions
cd intro-to-javascript-functions

Then, create an app.js and an index.html file. These files will hold your work for this lecture:

touch app.js index.html

With the files created, open the contents of the directory in VS Code:

code .

Open the index.html file and add HTML boilerplate by typing ! and then hitting the Tab key. Then make use of the app.js file by adding this line inside the <head> tag:

<script defer src="./app.js"></script>

With this setup complete, we’ll have two methods at our disposal for executing the code we write in app.js:

Open the index.html file in your browser and access the console output in your browser’s dev tools.
Use node to execute the app.js file directly by using this command in your terminal:

node app.js

While either method is acceptable, you should use the same method as your instructor for simplicity.
