Recursion task boilerplate missing arguments

[robertpenner]

Current boilerplate:

function getDependencies() {
// SOLUTION GOES HERE
}

Learners may take this literally and think they aren't supposed to use arguments in the function.

Yep, I was trying to avoid encouraging the 'additional parameter' recursion style over a different style (e.g. collecting results in a closure var + helper function). Maybe needs some additional comment.

[robertpenner]

But your solution has two arguments, so...?

[robertpenner]

In any case, the function needs at least one argument.

[timoxley]

Sure, but the second argument is not actually something that's passed to the function, it's just an implementation detail of the recursive step
