Please let us know what you liked, how we can improve, or feel free to ask follow up questions if you are still working through the workshopper.

I really like the workshopper modules. It's good to get our hands dirty on real problems. With that said, I think it would have been beneficial to get a primer on what functional programming is before diving in headfirst. Also, if someone could please give me a good explanation on what the hell a trampoline is, that would be great. All the stuff I found online isn't all that clear, at least to me.

@searsaw Thanks for the feedback, I totally agree on introduction content. I was not as prepared as I would like to have been. I would love to schedule another event specifically for this workshopper and plan on maybe a full hour group discussion before starting about functional programming in general, and it's application in node.js in particular.

The trampoline exercise definitely threw me at first as well. Here is what wikipedia offers, which probably doesn't help much.

I think about the trampoline function like this:

You jump once on a trampoline, and the trampoline continues to bounce you until it runs out of whatever initial energy you gave it.

You call a trampoline function (initial jump), passing it a function that when called executes its routine (float) and returns the next function to execute (bounce), and the trampoline function continues executing those functions until it runs out of functions to call.

Another attempt at trampoline explanation:

If you understand a waterfall pattern, where the result of each function is passed to the next function in the waterfall, this is similar. Except instead of yielding a result to a predefined set of steps, each step returns the next step. The 'waterfall' is done, when the last step does not yield the next step.

Good job, Jack!
