Same way:
var jsonEncodedString = JSON.stringify(string);
or are you asking for the revsere
var jsonString = JSON.stringify({hello:"world"}),
jsObject = JSON.parse(jsonString);
You can't convert a string into JSON. The outermost data type in JSON must be an object or an array.
See the specification:
JSON Grammar
A JSON text is a sequence of tokens. The set of tokens includes six structural characters, strings, numbers, and three literal names.
A JSON text is a serialized object or array.
You could wrap the string in an object or array and then serialise that:
JSON.stringify([myString]);
JSON.stringify({foo: myString});
Whatever processed it would have to know that after parsing the JSON it would have to extract the string from it though.

@Quentin.... suppose i have string like var str ="MyName" Am i able to use JSON.stringify(str)
Quentin
No! A string isn't a
[] or a {}Mihir
SO then need to parse like... JSON.parse({str}) or JSON.parse([str]) ?
Quentin
No. You pass a string (containing JSON) to JSON.parse and get a JS object back. If the JSON text starts with an object, you get an object. If it starts with an array, you get an array. You need to put an object or array into stringify not parse.
I think you're looking for the JSON.parse function.
var jsonString = '{"firstname":"Jesper","surname":"Aaberg","phone":["555-0100","555-0120"]}';
var contact = JSON.parse(jsonString);
var fullname = contact.surname + ", " + contact.firstname;
// The value of fullname is "Aaberg, Jesper"
