Difference between async callback notation?
What is the difference between:
cors(async (req, res) => {
// ...
})
and:
cors(req, res, async => {
// ...
})
The result is the same. I can't get my head around it.

It would be great to know the signature of your function cors. With a standard implementation the results can't be same.
The first cors call does the following:
it calls cors with just one parameter. This first and only parameter is a function with two parameters req and res and a promise result.
The second cors call does this:
it calls cors with three parameters. The first two parameters are not very interesting req and res. The last parameter is a synchronous function with one parameter called async
Could you provide a better example with input and output?
