The data argument represents the JSON data returned by jQuery.

When Dave mentions this (title), does he mean the data argument returns what came back from our $getJSON() and because of this it is now in JavaScript format?

Hi Nicholas,

Around the 5:00 mark in the video Dave mentions that jQuery parses the returned JSON data for you and so by the time it is passed into your handler it is in javascript format ready for you to retrieve values from it.

Here's a quote from the jQuery docs, http://api.jquery.com/jquery.getjson/

The success callback is passed the returned data, which is typically a JavaScript object or array as defined by the JSON structure and parsed using the $.parseJSON() method. It is also passed the text status of the response.

I think that this is what Dave is referring to.

Yea, so we are parsing to our function what the callback receives (which is an object in this case).
