That single line explained more of map-filter-reduce than the articles I've been reading has! Not directed at the author, to be clear, it was a genuinely great article--I just have been puzzling over it because something has been tripping around in my brain and BAM, this comment did it. My bachelor's is in math and so the map-filter-reduce descriptions sounded so close and yet so far to what I kept almost thinking and that particular one-line tripped the right memory circuits!


Is there something I missed that I could have done better?

I tried to make it as simple as possible, and I'm sorry if it did not simplify things for you.

No, not at all! I tried to make that clear, and failed. Your article was wonderfully written--it's just a topic that I've been chewing on for awhile and has eluded me, and that random one-liner reminded me of past math classes and was the final link, as it were. I really loved your piece!
