Hi @justsml - Thanks so much for this! This is great. I will merge this in when ready.

note: @shiffman we definitely should address this across our examples.

[justsml]

Thanks @joeyklee 🤘

Let me know if I need to make any changes.

Hi @justsml - I made a note about where the sketch.js file should live below. Would it be possible to undo that revision?

[joeyklee]

Correct me if I'm mistaken, but we should always try to leave the sketch.js at the end of the body tag to make sure that the DOM elements are loaded before calling the script.

This example will work fine this way, but for consistency, we should just always call script.js at the end of the index.html.

[justsml]

Thanks for the reply!
That sounds about right, I'll have time to hack on it later today 🤘

[joeyklee]

Thanks a bunch! Let me know whenever you're ready and I can review. If you're able to resolve any of the merge conflicts that would be great, otherwise I can also take care :)

Many thanks!
