It is just a different representation of the same string: browser console outputs a simple readable representation as a visible text, Node,js console outputs a source code representation, i.e. what you need to write in the code to get this string. Try in both consoles c === 'duan\x5cchao'.

Thanks for relpy, I want replace "?" to "".
input: "duan?chao"
output: "duan\chao"

Your code seems valid for this purpose.

no no, It return "duan\\chao" (2"\") in node.js,
I want to return "duan\chao" (1"\") like execute this code in browser.

It is just displayed this way in the Node.js console, with escaped backslash. Both results are identical, they have the same length and characters. You can check c.length or c.split('') in both consoles.

Yeah, I get it, thank you very much.
