`Symbol.split` 指向 一个正则表达式的索引处分割字符串的方法。 这个方法通过 `String.prototype.split()` 调用。

详情请参阅`RegExp.prototype[@@split]()` 和`String.prototype.split()`.

`Symbol.split` 属性的属性特性：
writable | false
enumerable | false
configurable | false

## 示例

[Symbol.split]指向‘aba’.split(/a/)

    /a/[Symbol.split]('aba',3)

"dayinlove".split(exp)调用[Symbol.split](str)处理，并把实参"dayinlove"传给形参str

    var exp =  {
            pat:'in',
            [Symbol.split](str) {
              return str.split(this.pat);
              }
        }

        "dayinlove".split(exp);
    //["day", "love"]
