: function used by assertArraysEqual() to check values of arrays -
eqObjects()
: function used by assertObjectsEqual() to check values of objects -
countLetters()
: returns an object where each key-value pair is a letter that appears in the passed-in string & how many times it appears -
countOnly()
: receives an array and an object that determines which items in the array will be counted -
