两个数组做比较，把数组中相同元素删掉，然后组成新的数组

//需求：两个数组做比较，在ary01里把含有ary02的元素删掉，组成新的数组ary03
let ary01=[1,2,3,4,5]
let ary02=[1,5]
let ary03=[]
for (var i = 0; i < ary01.length; i++) {
          for (var j = 0; j < ary02.length; j++) {
            if (ary01[i] == ary02[j]) {
              ary01[i] = "";
              break;
            }
          }
        }
console.log(ary01)//["",2,3,4,""]
for (var i = 0; i < ary01.length; i++) {
          if (ary01[i] != "") {
            ary03.push(ary01[i])
          }
        }
console.log(ary03)//[2,3,4]
