Starting with the Winter ’12 release, Apex includes native support for JavaScript Object Notation (JSON). Using Apex JSON classes, your Apex code can now parse JSON content and serialize Apex objects into the JSON format. The addition of native JSON support provides many benefits for Apex development, including efficient processing of JSON for HTML5 apps.

For this third developer challenge, build a demo app that leverages Apex JSON and then write an article that explains its source code. The winning entry receives a US$1000 gift card and gets their work published on Developer Force.
