(Not a JS'er) You can pass a comment as a parameter?

not in the language itself, but you can obtain the full text of a function, detect the comment and parse it, and inject it where ever it needs to go.
STRML
Yep. "Passing a comment" is used by calling .toString() on the function. It fails when using minification for obvious reasons but of course you wouldn't on Node code.

It's a clever hack around JS's awful multiline string support. But with ES6 template strings it's not really needed anymore.

You can, but I'm a little confused as to why you would, instead of just passing a string.

Fits in with the esoteric nature of the library, though.

Possibly because multiline strings are not supported?
ivank
ES6 template strings can span multiple lines.

But why?

It gives you a way to connect your enterprise system to your corporate intranet.

Seems like a pretty stupid way to do it. Why not just use the raw data from the data files or direct access to the DB/2 database? Does this even handle the ebcdic to ascii conversion? Or packed decimal numbers?

The same reason you could write part of your site in COBOL (Micro Focus) because you have a large body of legacy and need to get to the web.

Every time I was reading about old COBOL systems, I was wondering if we can compile COBOL to asm.js, this is slightly other direction but IMHO this topic requires more love.
