Lodash is an incredible accomplishment, and having it vastly improves the Javascript authorship process over the standard library.

That being said, I still can't believe we don't have a flatMap:

He explained how to add a flatMap in 2 lines in the first linked issue. It sounds pretty trivial to add per app.
