这段代码的作用是初始化一个二维数组 `_grid`,并将其中部分位置标记为 `'wall'` 或者 `'through'`。具体来说,代码中使用了两个嵌套的 `for` 循环,分别遍历二维数组中的每个位置。如果当前位置满足一定的条件,就将其标记为 `'wall'` 或者 `'through'`。在这段代码中,具体的条件如下:
- 第一行所有位置都被标记为 `'wall'`;
- 第二行中第 1、11、17 个位置被标记为 `'wall'`,其余位置被标记为 `'through'`。
这样一来,初始化完成后,二维数组 `_grid` 中的元素将如下所示:
```

```
其中,`wall` 表示墙壁,`through` 表示通道。
