• without(source, unwantedElements): Returns a new array from an argument array with elements removed per the other argument array provided.
• head(array1): Returns a new array with the element at index 0 of the argument array.

• countLetters(string1)): Returns an object with keys representing the characters and values representing their number of occurrences in a string.
