How to escape double quote in JSON string

Question

I am trying to do parse a string Hello " test containing double quote which already escaped, but I get an error

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

Is there anything I missed here?

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

Answer 1

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

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

Answer 2

let mydata = `{"x":"Hello \" test "}`
 
let escapeJsonFunc = function(str) {
    return str.replace(/\\/g,'\\');
};


console.log( escapeJsonFunc(mydata) )
