If your code is sufficiently distinct that block scope is useful, and there's no obvious contextual clue as to why it's distinct (like an if statement), put it in a separate function to explain why it's distinct. The article mentions this argument, but responds with some handwaving about how technically it's valid JS to use an unnamed block statement. I mean, sure, but does that mean it's a good idea?

I’ll just cross my fingers for do expressions getting adopted. Before then functions work for me and none of the gist convinced me otherwise.

How about don't use let or var declarations at all?

I had no ideas this was an option in JavaScript.

Fun read.
