I stopped maintaining it because it required a stupendous amount of time. That's fine except I had mostly stopped using it myself for the last 2 or 3 years I was maintaining it and I wanted the freedom to use that time to explore other unrelated projects.

Simultaneously the visibility around that project got me hired more than once, but my interest in doing JavaScript for employment was fading as well. I still write JavaScript/TypeScript in personal projects to this day, but I do completely unrelated work now for employment.
