What do I mean by functional? I'll get into that, but if you don't already know about it, you'll want to.
There's a bit of a learning curve but functional programming can speed up your development time and make your code much more maintainable and testable.
It's also super rad.
A word about this site
I can write in markdown as well as plain old HTML, and as soon as I do, I see the preview of my post in real time.
Pretty cool. It's also open source, so I'll be digging int the code and telling you all about what I've learned.
