Experiment short-circuiting of union distribution by Zzzen · Pull Request #50640 · microsoft/TypeScript

Zzzen (Zzzen) · 2022-09-05T15:48:35Z

Tried the following code on my machine, the check time is reduced from 24s to 6s. I'd like to see how it works for RWC.

type HugeUnion1 = "a" | "q" | ... [10,000 more];
type HugeUnion2 = "a" | ... [10,000 more which do not include 'q'];

type Square<T, U> = T extends U ? true : false;

type M = Square<HugeUnion1, HugeUnion2>;

Heya Jake Bailey (@jakebailey), I've started to run the perf test suite on this PR at 8f978fd. You can monitor the build here.

Update: The results are in!
