## Description
|
||
<section id="description">与字符串不同，数组的条目是<dfn>可变的</dfn> ，可以自由更改。 <strong>例</strong> <blockquote> var ourArray = [50,40,30]; <br> ourArray [0] = 15; //等于[15,40,30] </blockquote> <strong>注意</strong> <br>数组名称和方括号之间不应有任何空格，如<code>array [0]</code> 。尽管JavaScript能够正确处理，但这可能会让其他程序员在阅读代码时感到困惑。 </section>
|
||
|
||
## Instructions
|
||
<section id="instructions">将存储在<code>myArray</code>索引<code>0</code>处的数据修改为值<code>45</code> 。 </section>
|
||
|
||
## Tests
|
||
<section id='tests'>
|
||
|
||
```yml
|
||
tests:
|
||
- text: '<code>myArray</code>现在应该是[45,64,99]。'
|
||
testString: assert((function(){if(typeof myArray != 'undefined' && myArray[0] == 45 && myArray[1] == 64 && myArray[2] == 99){return true;}else{return false;}})());
|
||
- text: 您应该使用正确的索引来修改<code>myArray</code>的值。
|
||
testString: assert((function(){if(code.match(/myArray\[0\]\s*=\s*/g)){return true;}else{return false;}})());
|
||
|
