Why can't I just have one line in the function, rather than having to create a new array, populate it, and then count the elements? Such as: return count(get_products_all());

Hampton Paulk might be able to update this answer, or maybe explain why it's a little long winded.

5,891 PointsThis was on a code challenge. The single line was not accepted, but the three lines were. It is a function to get the count of the number of elements in an array. This is my code from Mike's store, I think the code challenge used $flavors but it is the same thing.
function get_products_count() {
$products = array();
$products = get_products_all();
return count($products);
}
versus
function get_products_count() {
return count(get_products_all());
}

Unless there's a good reason that these variables have to be defined regardless. What's the original function?

5,093 PointsTom is right, your code is smaller for sure. The code challenges are very picky, testing you in the way it was taught. I understand the frustration for sure.
