• tail: Returns every item after the first item in an array.
• assertArraysEqual: Asserts whether two arrays are equal.
• assertEqual: Asserts whether two primitive values are equal.
• assertObjectsEqual: Asserts whether two objects are equal.
• countLetters: Returns an object containing each unique character in the given string as a key and the property will contain the number of occurrences of that character.
• countOnly: Given an array and an object, the function will return an object containing counts of everyhting that the input object listed and was contained in the array as well.
• eqArrays: Compares the data of two arrays and returns whether or not they are equal.
• middle: Returns only the middle elements of an array - the two in the middle for an array with an even .length, and the one in the middle for an array with an odd .length.
• eqObjects: Compares the data of two objects and returns whether or not they are equal.
• findKey: Takes an object and a callback and returns the first item in the object for which the callback returns a truthy value.
