How do you keep your reusable Storyline JS bits in sync across projects?

I'm a really big fan of OneNote as a productivity tool, so I use it often. It makes a great library, and I have a small section for snippets or links to snippets.

I'm the only one on my team who knows any JavaScript. I'm building out first-steps for a few people, but they're at the "what is a boolean?" point still. That also means there's no larger JS development at our company or handing off of major, coded learning projects.

As long as they don't contain any proprietary information, I've imagined code snippets could live in JSFiddle or something so they can be accessed on any browser, but I never seem to either work on projects that leverage reusable snippets or find ones useful enough to use again much less hang onto.

To the other end of the spectrum, I've been spending the last couple years really exploring how to create JavaScript engines in Storyline, such as are used in simulations. I have a 2D grid-based movement engine that's coming along nicely and is definitely over 1,000 lines. For that, I simply added a .js in the directory Storyline uses to publish content that I edit in VSC. Ctrl+S to "push" the changes from VSC to Storyline, and then Preview to see them in action.

I hadn't really thought about it, but with a mature enough implementation, the code could be hosted on Github and retrieved at runtime via CDN. Neat.
