• countLetters: Returns an object with the frequenecy of each letter of a given string.
• countOnly: Acepts an array of strings and an object of strings with T/F values that dictate which strings are to be counted. Returns an object with the frequency of each string ex. countOnly(bill, bob, {bill: true, bob: false})
• findKey: Returns the key from an input object whose value passes the criteria of a callback function findKey(object, callback)
• findKeyByValue: Given an object and a value, this function will return the corosponding key findKayByValue(obj, value)
• letterPositions: Returns an object containing each letter as a kay and an array of each index occurance of that letter as a value letterPositions(string)
• map: Returns an array with the callback function applied to each array element map(arr, callback)
• takeUntil: Returns an array with each element of the input arr UNTIL the callback no longer accepts. takeUntil(arr, callback)

• assertArraysEqual: Compares (T/F) Arrays

• assertEqual: Compares (T/F) simple ===
• assertObjectsEqual: Compares (T/F) Objects
• eqArrays: Compares (T/F) Arrays
• eqObjects: Compares (T/F) Objects
