let maxObj = objects.reduce((max, obj) => (max.votes > obj.votes) ? max : obj);

/* `max` is always the object with the highest value so far. 
 * If `obj` has a higher value than `max`, then it becomes `max` on the next iteration.
 * So here:
 *  |  max = {id: 0, votes: 5},   obj = {id: 1, votes: 3}
 *  |  max = {id: 0, votes: 5},   obj = {id: 2, votes: 11}
 * reduced = {id: 2, votes: 11}
