Create a helper function that receives a collection and returns a copy if its an array and converts to an array if collection is an object. Used helper function to create functions for own versions of each, map, reduce, find, and filter. Also created functions to get size of collection as well as first and last elements of a collections. Additionally created functions to work with objects. One function returns the keys of an object. The second functions uses the key of an object to interate and return an array with the values of the passed in object.
