计算1 - 100之间所有奇数的和，偶数的和，3的倍数的和

var num = 1;            
var num1 = 1;
var oddSum = 0;
var evenSum = 0;
var timesSum = 0;
      while(num <= 100){
           if (num % 2 == 0) {
                evenSum = evenSum + num;
           }else if (num % 2 == 1) {
                oddSum = oddSum + num;
           }
                num++;
       }
      while (num1 <= 100){
        if (num1 % 3 == 0) {
            timesSum = timesSum + num1;
            }
            num1++;
      }
       console.log("偶数" + evenSum,"奇数" + oddSum,"3的倍数" + timesSum)
