This is very cool. I remember I got sucked into things like Ramda going down this functional programming rabbit hole :-)

The first thing I did when I encountered js in the 90s was write map and reduce. After leaving Mozilla I published a npm package with my hacks. I was very happy to find someone else had done a much better job at it and was actually maintaining it.

also, have you seen lazyjs? Also very cool.
