← Back to context Comment by codebje 3 months ago Alas, no: foo.ts:1:10 - error TS2393: Duplicate function implementation. 2 comments codebje Reply wk_end 3 months ago Like this:https://www.typescriptlang.org/play/?#code/GYVwdgxgLglg9mABA...It's a bit of a hack, though - if you incorrectly implement myFunc so that, say, it returns a string even when x is true, it can violate the overloading assertions without any error or warning. codebje 3 months ago Thanks! If anyone else is playing along, to get this to work with tsc I needed to use "--strict".Being able to use a function along those lines in a type safe manner is still pretty nifty, even if you can't write it with type safety.
