When I started trying to get to grips with the Fantasy Land spec and its uses, I spent most of my day with this expression:
The thing is that a lot of these patterns are going to be pretty weird if you're coming from a different paradigm (most likely OOP). In any case, it's probably going to be helpful to have some examples. With that in mind, I'm going to fill this repo with exactly that, and refer to it whenever I get stuck.
I'll aim to include all examples and exercises from the blog series, as well as some new ones as I stumble across them. If you want to contribute, please submit pull requests with updates to the current examples, or even exciting new stuff! All discussion is productive, and (if you haven't guessed) I love talking about this stuff. Heads up: I intend to uphold a code of conduct, as we're all hopefully more interested in functional programming than upsetting each other. I'm optimistic!
Finally, ask questions! I'm by no means an expert, but I'll do my best to be useful, or at least point you in the direction of more helpful people. I don't know about you, but I like the idea of a functional future for JS, so it's totally in my best interests to clarify anything that might confuse people.
