# --description--
您也可以在其他數組中嵌套數組,如:
```js
[["Bulls", 23], ["White Sox", 45]]
```
這也叫做多維數組(<dfn>multi-dimensional array</dfn>)。
# --instructions--
創建一個名爲 `myArray` 的嵌套數組。
# --hints--
`myArray` 應該至少有一個數組嵌套在另一個數組中。
```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
var myArray = [];
```
# --solutions--
```js
var myArray = [[1,2,3]];
```
