How to convert boolean and number type Json Key value to string type

I'am having a json object where it has different key values of string,boolean and number type.I want to convert the boolean and number type key value to string type..i.e.,eg:{"rent":2000,"isPaid":false} which is a valid json .Here i want to convert rent and isPaid to string type i.e.,{"rent":"2000","isPaid":"false"} which is also valid.for this I'am using replacer, but not working exactly how I require:

var json={"rent":2000,"isPaid":false};
var jsonString = JSON.stringify(json, replacer);
function replacer(key, value) {
if (typeof value === "boolean"||typeof value === "number") {
return "value";
}
return value;
}
console.log(jsonString);

Then above code is consoling as: {"rent":"value","isPaid":"value"}

Then I replaced return "value" with return '"'+value+'"' .Then on console it is giving {"rent":"\"2000\"","isPaid":"\"false\""}

So can someone help me so that it returns as {"rent":"2000","isPaid":"false"}

Any help is appreciable! Thanks!

There is some reference, using JSON.parse(text[, reviver]) "reviver" parameter.

    let reviver = (key, value) => 
    (typeof value === 'number' || typeof value === 'boolean') ? String(value) : value;

You can use JavaScript's toString() method to convert numbers/boolean to change them to string, as below:

var json={"rent":2000,"isPaid":false};
var temp = {};
json.forEach(function(val, key)
{
 temp[key] = val.toString();
});
json = temp;

You can do it by this way...

var json={"rent":2000,"isPaid":false};
var jsonString = JSON.stringify(json, replacer);
function replacer(key, value) {
if (typeof value === "boolean"||typeof value === "number") {
return value=""+value+"";
}
return value;
}
console.log(jsonString);

Try this:

var json={"rent":2000,"isPaid":false};
var jsonString = JSON.stringify(json, replacer);

function replacer(key, value) {
  if (typeof value === "boolean"||typeof value === "number") {
    return String(value);
  }
  return value;
}

console.log(jsonString);

We're using the String() function to convert your booleans and numbers to string. The output is:

{"rent":"2000","isPaid":"false"}
