javascript webpack配置

题目1:数组查找指定和的下标 ``` 输入：nums = [2,7,11,15], target = 9 输出：[0,1] 解释：因为 nums[0] + nums[1] == 9 ，返回 [0, 1] 。

*** 尝试双层遍历 ***

return{
    isAdgust: true,
    arr: [],
    target: 0,
    newArr: [],
}   },   methods: {
checkIndex: function (arr, target) {
    this.arr = arr;
    this.target = target;
    this.newArr = [];
    for(let i = 0; i < arr.length; i++){
        for(let j = 1;j<=arr.length;j++){
            if(arr[i]+arr[j]===target){
                this.newArr.push([i,j]);
            }
        }
    }
  this.isAdgust = false;
  console.warn(this.newArr);
},   }, ```
