They know that, because that was the premise of what they were trying to do:

You wrote: "how does a js developer use `guix shell` to load a js line 
like node-rimraf in a repl currently`:

In particular: "load a js like node-rimraf" = run node-rimraf (or in my 
example, node-mersenne).

Also, given that the question contains 'node-SOMETHING', I think it's 
clear that they wanted to use the _node_ REPL (and not, say, the Guile 
REPL).
