Fill in line 14 and line 15 to make this work:
<script>

  function larger(o1, o2) {
        if ( o1.size > o2.size ) {
            console.log('o1 is larger');
        } else {
            console.log('o2 is larger');
        }
    };
    
 

    var x = ; // write code here;
    var y = ;// write code here
    
    larger(x, y);    



</script>
