• countOnly(array, object): returns an object with strings as keys that detail how many times those strings appeared in the array of strings.
• eqArrays(array1, array2): returns boolean if arrays are equal
• eqObjects(object1, object2): returns boolean if objects are equal
• findKey(object, function): returns value of key in object that is specified in the callback function
