Why does "arr" reference the "playlist" array? Is that the nature of "arr" itself or is it assigned?

Guil uses "arr" to reference the array at the top of the page but I don't ever see him assign the array to "arr".

The createListItems function uses "arr" as the parameter name. So within the function definition, the array is referred to as "arr".

It doesn't get associated with the actual array until the function is called with createListItems(playlist) later in the code.
