Converting an object to JSON and back

JavaScript Object Notation (JSON) is very closely related to JavaScript objects because it's a subset of JavaScript. This task will demonstrate how to use the building blocks of JSON conversion: JSON.parse and JSON.stringify.

Getting ready

We'll need to create two new files called profiles.js, which will hold the data we'll be converting into JSON and back.js, which will be our main file for this recipe.

How to do it…

Let's create the object that we'll later be converting to JSON, in profiles.js as follows:

module.exports = {
  ryan: {
    name: "Ryan Dahl",
    irc: "ryah",
    twitter: "ryah",
    github: "ry",
    location: "San Francisco, USA",
    description: "Creator of node.js"
  },
  isaac: {
    name: "Isaac Schlueter",
    irc: "isaacs",
    twitter: "izs",
    github: "isaacs",
    location: "San Francisco, USA",
    description: "Former project gatekeeper, CTO npm, Inc."
  },
  timothy: {
    name: "Timothy J Fontaine",
    irc: "tjfontaine"...
