Hey Curtis, thanks for writing back.
As with a lot of things, it really comes down to personal preference.
I've used TypeScript for almost two years now, both at work and on pet projects and I've found it much preferable to just write types for everything rather than have the cognitive load of thinking "this probably doesn't need a type".

It also has an added benefit of improving your IDE experience by offering you better auto completes.

Also, you raise a valid point about the gameState type. To be honest, I wanted to avoid confusing people by rewriting some of the existing logic and just stick to writing types, but this is an excellent place to put the tuples to use. I'll make sure to update it in part two!

Well, for TS lines below are equal. There is no difference in IDE experience (autocomplete, e.t.c).

let gameActive: boolean = true;
let gameActive = true;

Just turn on noImplicitAny option in your tsconfig.json and TS will yell at you where a type can't be inferred. No extra cognitive thinking is required 😂
