The JSON.stringify() method is used to print the JavaScript object. This method is used to allow to take a JavaScript object or Array and create a JSON string out of it. While developing an application using JavaScript, many times it is needed to serialize the data to strings for storing the data in a database or for sending the data to an API or web server. The data has to be in the form of the strings. This conversion of an object to a string can be easily done with the help of the JSON.stringify() function.Â
Syntax:
JSON.stringify(value, replacer, space)
Example 1: This example converts the object to a string by simply traversing it and appending the object property and value to the string.Â
Javascript
let GFG_object = {    prop_1: 'val_11',    prop_2: 'val_12',    prop_3: 'val_13'};Â
let printObj = function (obj) {Â Â Â Â let string = '';Â
    for (let prop in obj) {        if (typeof obj[prop] == 'string') {            string += prop + ': ' + obj[prop] + '; \n';        }        else {            string += prop + ': { \n' + print(obj[prop]) + '}';        }    }Â
    return string;}Â
console.log(printObj(GFG_object)); |
prop_1: val_11; prop_2: val_12; prop_3: val_13;
Example 2: This example using the JSON.stringify() method to convert the object to string.Â
Javascript
let GFG_object = {    prop_1: 'val_11',    prop_2: 'val_12',     prop_3: 'val_13'};   console.log(JSON.stringify(GFG_object)); |
{"prop_1":"val_11","prop_2":"val_12","prop_3":"val_13"}
