jQuery UI Drag and Drop with FunScript

If you've been keeping up with activity in the F# world, you have no doubt seen great strides in a number of areas such as expansion of support for F# on different platforms and an ever increasing number of libraries and frameworks. One of these libraries that I've been playing with of late is named FunScript.

What is FunScript?

The FunScript website provides a nice definition.
FunScript is a lightweight F# library that lets you rapidly develop single-page applications. You can connect to external data sources and call REST APIs with intellisense, produce dashboards using JavaScript visualization libraries and write asynchronous computations easily without explicit callbacks.
One of the cool features that FunScript provides is a TypeScript type provider that allows any TypeScript definition file to be used to generate strongly typed access to the associated JavaScript lib. Let's look at an example of how to do this.

jQuery UI Drag/Drop Example

In this example, we create a simple TODO type of application using jQuery UI, FunScript, and the TypeScript type provider that FunScript provides. You can find the full example with detailed comments on the FunScript GitHub site.
