TS's typing is opt-in and it'll infer any (i.e. whatever) if you don't specify a type or it can't be inferred easily. Gradual typing is the best of both worlds

TS's typing is opt-in and it'll infer any (i.e. whatever) if you don't specify a type or it can't be inferred easily. Gradual typing is the best of both worlds here: you can quickly code up something and then later add types as you wish. Personally, I like types because entire classes of errors and bugs no longer apply without me having to think.
