Spreading a tuple type in TypeScript doesn't work

Question

slikts opened this issue 6 years ago · 1 comments

tuple(...[a, b]) causes a TS error: [ts] Expected 0-8 arguments, but got 0 or more.

It's supposed to be resolved in microsoft/TypeScript#24897.

Works in current versions of TS: Tuple(...[1,2,3] as const).
