Typescript Pain. Is there any Gain?

Randy is diving back into the Chasms backend using Firebase Functions, which is written (by him) in Typescript. We discuss the ins and outs as to why Typescript was chosen, some pain points that cropped up along the way, Randy's attempt to rip it out, and ultimately why sticking with Typescript was necessary in this particular case.
