# --description--
|
|
|
|
您也可以在其他数组中嵌套数组,如:
|
|
|
|
```js
|
|
const teams = [["Bulls", 23], ["White Sox", 45]];
|
|
```
|
|
|
|
这也叫做多维数组(<dfn>multi-dimensional array</dfn>)。
|
|
|
|
# --instructions--
|
|
|
|
创建一个名为 `myArray` 的嵌套数组。
|
|
|
|
# --hints--
|
|
|
|
`myArray` 应该至少有一个数组嵌套在另一个数组中。
|
|
|
|
```js
|
|
assert(Array.isArray(myArray) && myArray.some(Array.isArray));
|
|
```
|
|
|
|
# --seed--
|
|
|
|
## --after-user-code--
|
|
|
|
```js
|
|
if(typeof myArray !== "undefined"){(function(){return myArray;})();}
|
|
```
|
|
|
|
## --seed-contents--
|
|
|
|
```js
|
|
// Only change code below this line
|
|
const myArray = [];
|
|
```
|
|
|
|
# --solutions--
|
|
|
|
```js
|
|
const myArray = [[1, 2, 3]];
|
|
```
