Unit 4: JQuery and Structured Data
In this unit, we will take a brief look at JQuery, a mechanism for direct access to the document object model within a script. Since mobile applications often need to interact with a service, we will also look at how data between the service and the mobile application is exchanged using either Extensible Markup Language (XML) or JavaScript Object Notation (JSON). We will compare and contrast both formats.
Completing this unit should take you approximately 11 hours.
