- Mogzol 6y agoThat's interesting. util.promisify normally only works with functions where the callback is the final argument, which isn't the case with setTimeout. I didn't know you could customize promisify behaviour, but looking at the docs apparently you can just by setting a property on the object using the util.promisify.custom symbol [1]. That is what setTimeout is doing, which is why that code works.
