Object to string, and vice-versa

Question

Say I had the object:

var object = {
    1: [2,5,"hi"],
    hi: {hihi: 1}
};

How would I convert that to a string, and then back, preserving all the information? I would need this to work for a big object, with the values themselves being objects.

This is not a duplicate, the others didn't involve getting the object back.

[`JSON.stringify()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify) is your friend! — Ram, Sep 13 '15 at 22:18
Voting to reopen as not a duplicate because the supposed duplicate is about converting an object to a string, and this question is about how to convert and then retrieve. None of the answers in the duplicate mention `JSON.parse()`, which is an important part of the answer to this question. — Maximillian Laumeister, Sep 13 '15 at 23:41
@Vohuman You made a bad decision, next time please be more careful with your close votes. — peterh, Sep 14 '15 at 00:07
What makes it "bad"? Since the question has 3 open votes I'll reopen it! — Ram, Sep 14 '15 at 00:16
@Vohuman He wanted a 2-way conversion, while the dupe was only unidirectional. Thank you the reopening, and that you'd hear us. — peterh, Sep 14 '15 at 00:16

Below is a live demo of how you can convert an object to a string and back using JSON.stringify() and JSON.parse().

Open your browser console and you can see that all attributes are preserved after the conversion to a string and back.

var object = {
    1: [2,5,"hi"],
    hi: {hihi: 1}
};

console.log(object);

var strobj = JSON.stringify(object);

console.log(strobj);

var unstrobj = JSON.parse(strobj);

console.log(unstrobj);
