I am confused why we are using function?

I am confused why we are using a function to iterate though the function. I thought we only needed a For Loop to iterate through an array?

The for loop does the iteration, but having it in a function makes it easy to access the code from an interpolation token in the template literal.

It would be possible to make all this happen without using the function or the template literal, but it would take more code and would be a bit "messy".
