## 多行字符串
不要使用
不要這樣寫長字符串:
```
var myString = 'A rather long string of English text, an error message \
actually that just keeps going and going -- an error \
message to make the Energizer bunny blush (right through \
those Schwarzenegger shades)! Where was I? Oh yes, \
you\'ve got an error and all the extraneous whitespace is \
just gravy. Have a nice day.';
```
在編譯時, 不能忽略行起始位置的空白字符; “\” 后的空白字符會產生奇怪的錯誤; 雖然大多數腳本引擎支持這種寫法, 但它不是 ECMAScript 的標準規范.
