open console and type
打开控制台和类型
'\'.replace(/\\/g, '\'); fails because the slash in the string isn't really in the string, it's escaping '
失败,因为字符串中的斜杠不在字符串中,它正在逃避'
'\\'.replace(/\\/g, '\');works because it takes one slash and finds it.
有效,因为它需要一个斜杠并找到它。
your regex works.

You can use String.raw to add slashes conveniently into your string literals. E.g. String.raw`\a\bcd\e`.replace(/\\/g, '\');
您可以使用String.raw方便地将斜杠添加到字符串文字中。例如。 String.raw` \ a \ bcd \ e`.replace(/ \\ / g,'\');
