I would prefer to split out the callback function definitions entirely for learning purposes. I have 4 or 5 students who aren't confidently able to distinguish a function definition from a function call as is, so I think it'd be cool to keep em separated.

Afaik we haven't shown them anonymous functions (edit: not even accidentally). Both classes have seen

var numbers = [1, 4, 9];
function doubler(num) {
  return num * 2;
}

var doubles = numbers.map(doubler);

and

var numbers = [1, 4, 9];

var doubles = numbers.map(function doubler(num) {
  return num * 2;
});

As a compromise, considered named callback-functions. Somehow it always feels like it makes more sense to them since it just looks like a normal function. Whereas both anonymous functions and function references look weird.

It's the missing, intermediate step:

numbers.map(function doubler(num) {
  return num * 2;
});

I think you showed them both today(20160316), right @bgveenstra ?

Thanks for the responses both of you. 🍔

@tgaff No anonymous functions today. Just the named inline callback definition and the separate named callback definition.

Great! That's what I meant! I think Will is going to repeat that in the review tomorrow too.
