下面看个例子就清楚多了

```js
const arr1 = ['a', 'b',[1,2]];
const arr1 = ['a', 'b', [1, 2]];
const arr2 = ['c'];
const arr3 = [...arr1,...arr2]
arr[1][0] = 9999 // 修改arr1里面数组成员值
console.log(arr[3]) // 影响到arr3,['a','b',[9999,2],'c']
const arr3 = [...arr1, ...arr2];

arr1[2][0] = 9999; // 修改 arr1 中的数组成员值
console.log(arr3); // 输出 ['a', 'b', [9999, 2], 'c']

```
