Nomor tertinggi ke -2 dari array
var arr = [1,2, -3, 15, 77, 12, 55];
var highest = 0, secondHighest = 0;
// OR var highest = arr[0], secondHighest = arr[0];
for(var i=0; i<arr.length; i++){

}
}
console.log('>> highest number : ',highest); // 77
console.log('>> secondHighest number : ',secondHighest); // 55
