Thankfully it shouldn't! There are still yields happening under the hood, but in Generator<Yield, Return, Next>, Next is the return value of individual yields which there can be many (source of the issue is they must be a product type A & B), while Return is the value returned when .next() returns done:true, and since there is only 1 value there we don't have to worry about the same typing complexities.

It's very easy to convert from one to the other. function*(thing) { const x = yield thing; return x}
