Javascript documentation is out of date and minimal

I would love more docs on how JS works in Rails. It’s pretty much a mystery to me and I just try to not touch it once I get it working. Why do I need to yarn install ? What is yarn (I worked that out, but it was just dumped there one day)? What is package.json? What do the JS files do in the app, and why are they in the locations they are in?

For visibility, there’s a coordinated effort to write a Rails guide for Webpacker in this thread: JavaScript Documentation Coordination
