Implement a Queue datastructure using two stacks. Do not create an array inside of the 'Queue' class. Queue should implement the methods 'add', 'remove', and 'peek'. For a reminder on what each method does, look back at the Queue exercise.

const q = new Queue();
q.add(1);
q.add(2);
q.peek();  // returns 1
q.remove(); // returns 1
q.remove(); // returns 2
