// Implement a decorator function that takes
// a function as an argument and will track
// how many times the passed function was called.
function Add(x, y) {
return x + y;
}
var Add = countDecorator(Add);
Add(1, 1);
// -> 2 Dont pay attention to this number. The important part is we called the `Add` function once.
Add.callCount();
// -> 1
Add(2, 2);
// -> 4 Dont pay attention to this number either. The important part is we called the `Add` function again.
Add.callCount();
// -> 2

I was reading through others' code for ideas about this assignment and I noticed this comment you(Hank Yates) made. I am really confused because it seems like you say we need to replace the add function. However in the example above it looks like we are only passing the Add function to our decorator function; not reassigning add. I'm struggling to find a way to answer this question without reassigning Add.
