• countLetters(...): countLetters function that takes string as input and returns object counting the amount of each letter present in string

• countOnly(...): countOnly function which takes an array and an object as input, creates a count of object items occuring in array, returns an object with item as key and count as value

• eqArrays(...): eqArray function that checks if two arrays are equal
