  1. Use getWidenedTypeForVariableLikeDeclaration, instead of directly calling tryGetTypeFromEffectiveTypeNode. This requires some changes in the former function since it can't assume that the declaration has an initializer. See below for details.
  2. isOptional now calls isOptionalJSDocPropertyLikeTag.
  3. isOptionalJSDocPropertyLikeTag now handles JSDocPropertyTag (previously it was named isOptionalJSDocParameterTag).

getWidenedTypeForVariableLikeDeclaration now handles @param and @property tags. I switched a couple of places to use type guards and added a call to hasExpressionInitializer. Then, to avoid calling it twice, I moved a js-only check inside that block. I'm not certain it's the right thing -- the code is cleaner now, but I could have left it as-is and added casts instead. If performance is worse it's the first thing I'm going to try undoing.

Fixes #39111

Heya @sandersn, I've started to run the perf test suite on this PR at c11528a. You can monitor the build here.

Update: The results are in!

Yeah, I agree that the re-sequencing looks nicer. The isInJSFile check should be cheap since it's just a node flag check nowadays, anyway.
