I noticed Javascript is on the languages roadmap -- is there a blog post or doc about what that's going to look like?  Is it planned to be as powerful as Python in terms of packaging and dependency inference (e.g., could a webserver written in nodejs using npm dependencies be packaged/tested/ran)?

Right now, it's just getting linters and formatters in place, as with some other languages.

Packaging is a bit of an odd duck in JS/TS unfortunately. Not that it can't be done, just that its a compilation/transpilation step followed by a bundle and tree shake or whatever.

Then, everyone has their own dep manager + build tools

If you have ideas/recommendations though, that would be great!

It's definitely our highest priority next language, and we do want it to be as powerful as Python, within reason. One thing that will help get this done is finding orgs that can sponsor and support the work, which also gives them the opportunity to ensure that their use-cases are covered.
