我们仍然可以通过使用“换行符(newline character)”,以支持使用单引号和双引号来创建跨行字符串。换行符写作\n,用来表示换行: let guestList ="Guests:\n * John\n * Pete\n * Mary"; console.log(guestList);//一个多行的客人列表 例如,这两行描述的是一样的,只是书写方式不同: ...
`the newline character at the end of this line is included literally in this string` 请注意,当使用单引号界定字符串时,必须小心处理英语缩写和所有格,例如can’t和O’Reilly’s。由于撇号与单引号字符相同,必须使用反斜杠字符(\)来“转义”出现在单引号字符串中的任何撇号(转义在下一节中有解释)。
