Llewellyn and Bart got together to write the first pass at koans for Rx last night. We published the result on CodePlex today - here.
What's a koan?
It's an interactive excercise, using the lanaguage (features) and done in the editor to learn without a teacher. Kind of like directed hacking, just 'fix' each line and...learn. The most fun way to do this is with another developer - pair up, code and learn! If you like this format, you can try it out in other languages, such as C# - here.
A better way to handle asynchronous events - composable, complete and clever? Don't understand - try the koans, that's why we wrote it.
Let us know what you think. We plan to expand this set of koans soon.
