What are the Best JavaScript Opensource projects to contribute?

Whichever ones you find interesting

A project you like and that is ready to help new (especially first-time) contributors. You’ll know that if:

• they have a “Contributing” page that explains what they expect the process to be like and the scope of a PR, and/or
• there’s a vibrant community (Discord, for example) where you see first-time contributors’ questions answered patiently, and/or
• they have a label “good first issue” on their GitHub issues :)

My reasoning here is that I f a community is welcoming and supportive of beginners, it’s also supportive of folks with more experience.

I’m pretty sold on SolidJS in this regard.
