In my opinion, this is the greatest success “hack” there is. If you live in an environment that nudges you toward the right decision and if you surround yourself with people who make your new behavior seem normal, then you’ll find success is almost an afterthought.
Monads are in danger of becoming a bit of a joke: for every person who raves
about them, there’s another person asking what in the world they are, and
a third person writing a confusing tutorial about them. With their
technical-sounding name and forbidding reputation, monads can seem like
a complex, abstract idea that’s only relevant to mathematicians and Haskell
Forget all that! In this pragmatic article we’ll roll up our sleeves and get
stuck into refactoring some awkward Ruby code, using the good parts of monads to
tackle the problems we encounter along the way. We’ll see how the
straightforward design pattern underlying monads can help us to make our code
simpler, clearer and more reusable by uncovering its hidden structure, and we’ll
end up with a shared understanding of what monads actually are and why people
won’t shut up about them.
The accompanying video is short, snappy, and to the point.
