On my previous post I talked a little about Functional Programming, hoping to introduce it to newcomers and developers with no previous FP experience. Several people said it was not very precise and it didn’t explained some concepts (such as Monads or Functors) with the required level of details. Well, I do hope to achieve some detailing with this post. Nonetheless, I’ll still try to keep it light to those who never programmed functionally before. ...

Functional Programming has risen as a solution to most modern days problems, such as concurrency and scaling. For some, it is a mystique concept that applies only to Erlang, Haskell and other strange languages that are either too complicated or irrelevant. This is simply not true, and I’m going to show how to apply some functional programming concepts on non-functional languages. I’ll deconstruct the functional paradigm by first defining what ‘Functional Programming’ really means, then explaining common idioms and comparing the syntax. In the end, I’ll show how to make relevant changes to non-functional in order to follow the Functional Programming Philosophy. ...
