Yep. TypeScript !== JavaScript, but it's along a similar misdirection.

Then there's "let". I guess it's not hurting anything, but how useful an addition is it, really? How many nested, non function, blocks you got in your code, buddy, that you need a new scope for your nested for-loops and else-ifs?!?

Between things like forEach, map, filter, etc, I don't actually write very many manual loops anymore, and often use an IIFE for something that outgrows a ternary. Most of my "blocks" are functions.
