Parse a JSON string to an object in JavaScript

This post will discuss how to parse a JSON string to an Object in JavaScript.

1. Using `JSON.parse()` function

JavaScript provides the native implementation of JSON.parse() method to parse the string. It returns the object corresponding to the given JSON string or throws a SyntaxError when the string is invalid JSON.

var obj = '{ "name": "Max", "age": 23 }';

var json = JSON.parse(obj);

console.log(json);

Output: { name: 'Max', age: 23 }

To do the reverse, call the JSON.stringify() method.

var obj = '{ "name": "Max", "age": 23 }';

var json = JSON.parse(obj);

// …

var jsonString = JSON.stringify(json);

console.log(jsonString);

Output: {"name":"Max","age":23}

2. Using jQuery

The jQuery library also has the $.parseJSON() method. This method is deprecated now, and it is recommended to use the native JSON.parse() method instead of parsing JSON strings.

const { JSDOM } = require("jsdom");

const { window } = new JSDOM();

var $ = require("jquery")(window);

var obj = '{ "name": "Max", "age": 23 }';

var json = $.parseJSON(obj);

console.log(json);

Output: { name: 'Max', age: 23 }
