• assertArraysEqual(array1, array2): take two arrays and console.log appropriate message
• assertEqual(actual, expected): check if two values are equal
• assertObjectsEqual(actualObject, expectedObject): take two objects and console.log appropriate message
• countLetters(string): count letters in a string
• countOnly(array, object): take array and object, return object containing total of everything that the input object listed
• eqArrays(array1, array2): check if two arrays are equal
• eqObjects(object1, object2): check if two objects are equal
• findKey(object, callback): scan the object and return the first key for which the callback returns a truthy value. if no key is found, then it should return undefined
