• head: Returns the first element of an array

• letterPositions: Takes in a string and returns an object containing all the indices (zero-based positions) in the string where each character is found

• map: Takes in an array and a callback. Returns a new array based on the results of the callback. function.

• middle: Takes in an array and return the middle-most element(s) of the given array
