countLetters(sentence): returns how many times a letter is used in a string -
countOnly(allItems, ItemsToCount): returns how many instances of each string were found in the array of strings -
eqArrays(array1, array2): takes in two arrays and returns true or false based on a perfect match -
findKey(object, callback): returns the first key for which the callback returns a truthy value -

map(array, callback): returns a new array based on the results of the callback function -
