Paul Bone will be speaking about Tail Recursion. This is a good meetup to come to if you're new to functional programming or have not attended before.
Tail recursion is important, and new FP developers are taught early on how to achieve it, but it can be more subtle than many people realise. For beginners I expect the definitions and the examples of tail recursive and non-tail recursive code to be helpful. And for intermediate and advanced developers, there may be some surprises in the details. Particularly the differences between different languages, and the various patterns available to enable tail recursion or at least use less stack space.
The doors to get into the office lock at 6pm. If you come later than that you'll need to give me a call on[masked] to let you in.
