How to escape double quote in JSON string

[Marius]

I am trying to parse a JSON string 'Hello " test' containing double quote which already escaped.

Code: Select all

JSON.parse('{"x":"Hello \" test "}')

But I get error:

Code: Select all

Uncaught SyntaxError: Unespected Tocken t in JSON

Is there anything I missed here?

You just need to escape the backslash \, so it turns into two backslashes \\

Code: Select all

let obj = JSON.parse('{"x":"Hello \\" test"}')
console.log(obj)
