Usually we just omit the return type if it's undefined, though I'm interested to hear another opinion.

I think given that our docs aren't 100% complete in terms of listing return types, being explicit here is probably helpful for people.


Call all `before` callbacks to notify that a new asynchronous execution context
is being entered. If nested calls to `emitBefore()` are made, the stack of
`asyncId`s will be tracked and properly unwound.

#### `asyncResource.emitAfter()`

Call all `after` callbacks. If nested calls to `emitBefore()` were made, then
make sure the stack is unwound properly. Otherwise an error will be thrown.
