fix(lib): reorder Array#reduce/reduceRight overloads so generic <U> variant is tried first#10
Conversation
…ariant is tried first Fixes microsoft#7014. When TypeScript resolves overloads it picks the first matching one. The `reduce(callbackfn, initialValue: T): T` overload was listed before `reduce<U>(callbackfn, initialValue: U): U`, so `arr.reduce((acc, x) => ..., [])` inferred `T[]` instead of the expected `U`. Moving the generic `<U>` overload above the `T`-with-initialValue overload makes TypeScript try the more-specific version first. Applied to all four groups: ReadonlyArray.reduce, ReadonlyArray.reduceRight, Array.reduce, Array.reduceRight. Signed-off-by: creazyfrog <rohitcse.gec@gmail.com>
