How does the reduce call work in the reverse() example? about mostly-adequate-guide HOT 10 CLOSED

If you are talking from Chapter 5, reduce is actually _.reduce() from the Ramda library, which has been curried.

DrBoolean needs to prefix a few functions explicitly with _., so it's obvious they are coming from a library.

Thanks!

This construction is esoteric enough to non-Ramda users that a sidebar about how it operates would be worthwhile I think. As far as I can tell, the commonly-used underscore.js implementation of reduce() wouldn't allow this trick.

In particular I'm not understanding how reduce digests the empty array it's given in the example.

I have a video available that talks about reduce: https://www.youtube.com/watch?v=JZSoPZUoR58
