This is the code from my Modern JS From The Beginning course. It contains all of the learning modules and project code.
There is a folder called "javascript-sandbox-start", which contains the starter files for the learning modules and any themes (HTML/CSS) for the projects. You can use these to follow along with the course or create your own files as you go.
The premium markdown files with all code samples and explanation are included with the premium course at https://www.traversymedia.com/modern-javascript-2-0
