js根据一个数组删除另一个数组相对应的元素

arr1:父数组  arr2子数组

  function removePoint(arr1,arr2){
      for(let i=0;i<arr2.length;i++){
        for(let j=0;j<arr1.length;j++){
          if(arr2[i]== arr1[j]{
            let index = arr1.indexOf(arr1[j]);
            arr1.splice(index,1)
          }
        }
      }
    return arr1
}
let arr1 = [1,2,3,4,5,6,7,8,9,10,20,25];
let arr2 = [3,6,9,20]
remoovePoint(arr1,arr2)
输出：[1,2,4,5,7,8,10,25];
