JavaScript Array .at() method

The JavaScript array .at() method is used to get one specific item in an array of items.

It requires one parameter which is an integer number that represents the index of an item in an array.

When the parameter is positive, it returns the value of that index. When the parameter is negative, it traverses from the end of the array until it finds the index of that negative integer.
