新行在客户端和服务器端如何分类？

Question

I have the following object {g: "a\\nb"} that I stringify using JSON.stringify .

On the client side '{"g":"a\\nb"}' is returned but on the server side an escaping character is added: '{"g":"a\\\\nb"}' .

Chrome console

Google Chrome console view

Node console

> a = {g: "a\nb"}
{ g: 'a\nb' }
> JSON.stringify(a)
'{"g":"a\\nb"}'

Why is this happening?

Answer 1

This is a rendering issue, the results are equal. It just shows them differently in the Chrome console for clarity. It shows it in a more readable format.

The Node console doesn't do any such magic.

You can observe this in the chrome console:

JSON.stringify({g: "a\nb"}) === '{"g":"a\\nb"}'; // true
