For Loop

For-Each

.forEach takes a callback function, that callback function is expected to have at least 1, but up to 3, arguments. This is how .forEach was designed.

The arguments are in a specific order:
• The first one represents each element in the array (per loop iteration) that .forEach was called on.
• The second represents the index of said element.
• The third represents the array that .forEach was called on (it will be the same for every iteration of the loop).
