13:00 Why does "This is a" get called before "This is foo"?

It passes a function but every time it passes a function it passes a function

[@jeff-creations]

First time seeing one of your videos. Love it, one of the best presentations I have seen in a while. Clear and to the point. I now have a better understanding of functions. Thanks! Subscribed!

Trying to understand arrow functions and higher order functions in JS
I am stuck at this question:
"Write a function called useParameterToFilterArray that takes an anonymous function and uses that in the `unfilteredArray` filter function then return the result. let unfilteredArray = [1, 2, 3, 4, 5, 6]; //given"
what this question is actually trying to say? (cant wrap my head around)
could you help me understand this?

[@cjav_dev]

That prompt doesn't really make sense to me either 😅.
"Write a function called useParameterToFilterArray that takes an anonymous function..." looks like this:
function useParameterToFilterArray(filterFunction, array) {
}
"and uses that in the `unfilteredArray` filter function then return the result."
That part of the prompt doesn't really make sense.
I think what it intends is to _use_ that filterFunction on each of the elements in the array to create a new array that only contains elements that when passed into the filterFunction, returns true?
Technically, you could implement the function with array.filter(fn), but my guess is that's a bit of cheating, so this is a more raw implementation: gist.github.com/cjavdev/d7788a6b2abc64faf0ac4e1f65f2c698.
