split
方法用于把字符串分割成字符串数组,接收一个分隔符参数,分隔符可以是用于分解字符串或正则表达式的字符。举个例子,如果分隔符是空格,你会得到一个单词数组;如果分隔符是空字符串,你会得到一个由字符串中每个字符组成的数组。
下面是两个用空格分隔一个字符串的例子,另一个是用数字的正则表达式分隔:
var str = "Hello World";
var bySpace = str.split(" ");
// Sets bySpace to ["Hello", "World"]
var otherString = "How9are7you2today";
var byDigits = otherString.split(/\d/);
// Sets byDigits to ["How", "are", "you", "today"]
因为字符串是固定的,split
方法可以更简单的操作它们。

在splitify
函数中用split
方法将str
分割成单词数组,这个方法应该返回一个数组。单词不一定都是用空格分隔,所以数组中不应包含标点符号。
--hints--
应该使用split
方法。
assert(code.match(/\.split/g));
splitify('Hello World,I-am code')
应返回['Hello', 'World', 'I', 'am', 'code']
。
assert(
JSON.stringify(splitify('Hello World,I-am code')) ===
JSON.stringify(['Hello', 'World', 'I', 'am', 'code'])
);
splitify('Earth-is-our home')
应返回['Earth', 'is', 'our', 'home']
。
assert(
JSON.stringify(splitify('Earth-is-our home')) ===
JSON.stringify(['Earth', 'is', 'our', 'home'])
);
splitify('This.is.a-sentence')
应返回['This', 'is', 'a', 'sentence']
。
assert(
JSON.stringify(splitify('This.is.a-sentence')) ===
JSON.stringify(['This', 'is', 'a', 'sentence'])
);

splitify("Hello World,I-am code");

return str.split(/\W/);
