Where does rails log errors in javascript?

Question

I'm fairly new to Ruby on Rails so sorry if the answer is obvious, I couldn't find anything via search. Right now I have my view rendering _box.js.erb which simply draws a box. Inside _box.js.erb, which works correctly under normal circumstances, I introduce a simple syntax error like an unmatched parenthesis. When I load the webpage, my box doesn't show up. I look in logs/development.logs and it has no mention of my javascript syntax error. Is this error being caught somewhere? If so, how can I display it?

The error occurs on the client, not the server, so ROR cannot log it.

If you're using Firefox, install Firebug. Other browsers have JavaScript consoles, usually opened by pressing F-12 or looking on the "developer" options on the application menus.

Oh that makes sense, I forgot that JS is client side.

You could also create a controller to accept javascript errors, so when there's a client side error you can just send it to a javascript error collection endpoint which in turn could take the contents of the error and add it to the Rails log or whatever log.

This old gem does that. I realize this questions is 8 years old.
