# --description--
|
||
|
|
||
|
使用數組(`array`),我們可以在一個地方存儲多個數據。
|
||
|
|
||
|
以左方括號開始定義一個數組,以右方括號結束,裏面每個元素之間用逗號隔開,例如:
|
||
|
|
||
|
```js
|
||
|
var sandwich = ["peanut butter", "jelly", "bread"]
|
||
|
```
|
||
|
|
||
|
# --instructions--
|
||
|
|
||
|
創建一個包含字符串(`string`)和數字( `number`)(按照字符串數字的順序)的數組 `myArray`。
|
||
|
|
||
|
# --hints--
|
||
|
|
||
|
`myArray` 應該是一個數組(`array`)。
|
||
|
|
||
|
```js
|
||
|
assert(typeof myArray == 'object');
|
||
|
```
|
||
|
|
||
|
`myArray` 數組的第一個元素應該是一個字符串(`string`)。
|
||
|
|
||
|
```js
|
||
|
assert(typeof myArray[0] !== 'undefined' && typeof myArray[0] == 'string');
|
||
|
```
|
||
|
|
||
|
`myArray` 數組的第二個元素應該是一個數字(`number`)。
|
||
|
|
||
|
```js
|
||
|
assert(typeof myArray[1] !== 'undefined' && typeof myArray[1] == 'number');
|
||
|
```
|
||
|
|
||
|

## --after-user-code--
|
||
|
|

```js
|
||
|
(function(z){return z;})(myArray);
|
||
|
```
|
||
|
|
||
|
## --seed-contents--
|
||
|
|
||
|
```js
|
||
|
// Only change code below this line
|
||
|
var myArray = [];
|
||
|
```
|
||
|

```js
|
||
|
var myArray = ["The Answer", 42];
|
