Support automodule for JavaScript

[a-gertner]

First of all, thanks for this great package. I find it very useful.

I was trying to use .. automodule directive for JavaScript modules, but kept getting assertion error. After a very brief look at the source code I understand that .. automodule only works for TypeScript.

• Is my assumption correct or am I getting it all wrong?
• Is there an intention to implement automodule and maybe even autosummary for JS?

Thanks )
