## Description
|
|||
|
|
<section id="description"> <code>split</code>方法将字符串拆分为字符串数组。它接受分隔符的参数，分隔符可以是用于分解字符串或正则表达式的字符。例如，如果分隔符是空格，则会得到一个单词数组，如果分隔符是空字符串，则会得到字符串中每个字符的数组。下面是两个用空格分隔一个字符串的例子，然后用正则表达式用数字分割另一个字符串： <blockquote> var str =“Hello World”; <br> var bySpace = str.split（“”）; <br> //将bySpace设置为[“Hello”，“World”] <br><br> var otherString =“How9are7you2today”; <br> var byDigits = otherString.split（/ \ d /）; <br> //将byDigits设置为[“How”，“are”，“you”，“today”] </blockquote>由于字符串是不可变的，因此<code>split</code>方法可以更轻松地使用它们。 </section>

## Instructions
|

|
|
<section id="instructions">使用<code>splitify</code>函数内的<code>split</code>方法将<code>str</code>拆分为单词数组。该函数应该返回数组。请注意，单词并不总是用空格分隔，并且数组不应包含标点符号。 </section>
