Justin and Welsh want to introduce you to JSON. Not only is JSON (JavaScript Object Notation) a great tool for building and storing structured data in your 4D code, it's a great format to use when sending data between systems. JSON is widely used as a lightweight alternative for web app communication between browser and server, including Wakanda's Web Application Framework and also by the REST API in 4D v14. Knowing how to use it will be helpful, if not essential.

This session will give you an overview of the JSON standard, and then we'll dig in with examples. We'll build and use JSON objects in the available tools, including the new 4D v14 JSON commands, NTK (Networking ToolKit), and a new open source component that utilizes the libjson plugin developed by 4D's own Keisuke Miyako.
