What would you like to do?
This script goes through the votes object and it's nested object and counts the number of times that each candidate is voted for and then tallies them in a separate object. Then we need to somehow return a winner for each category.
/*
In this challenge you will work with the following JavaScript objects.
Do not alter these objects here.
*/
// I need to go through the votes object and look at each string which contains it's own object, then I need to go through
// each nested object and count how many times a canidites name comes up for each category in the votes count object and assign it
// to that object. We need to look at each property inside the nested objects and count how many times that value occurs.
// These are the votes cast by each student.
