/*
JavaScript Object Notation (JSON) is a standard format for representing structured data as JavaScript objects, which is commonly used for representing and transmitting data on web sites (i.e. sending some data from the server to the client, so it can be displayed on a web page). You'll come across it quite often, so in this article we give you all you need to work with JSON using JavaScript, including accessing data items in a JSON object and writing your own JSON.
JSON is a data format following JavaScript object syntax, which was popularized by Douglas Crockford. Even though it is based on JavaScript syntax, it can be used independently from JavaScript, and many programming environments feature the ability to read (parse) and generate JSON.
JSON can exist as an object, or a string — the former is used when you want to read data out of the JSON, and the latter is used when you want to send the JSON across the network. This is not a big issue —  JavaScript provides a global JSON object that has methods available for converting between the two.
A JSON object can be stored in its own file, which is basically just a text file with an extension of .json, and a MIME type of application/json.
