====== Functional Programming ======

Why Functional Programming (FP)?

I do not oppose object oriented programming (and think that OO can coexist nicely with FP), rather, I believe that a style of programming that embraces the advantages of both OO and FP can realize significant benefits.  For example:

  * Easier tests with fewer fixtures and mocks, that refactor cleanly with the production code
  * More natural parallelism.  
    * Using a functional architecture, often parallelism can be added automatically as a feature of the library, without requiring synchronization or locking.
    * With multiple cores being standard equipment on today's computers, having natural parallelism that you just switch on is a huge advantage.

Put quite simply, a functional style of programming can be achieved in any programming language, from //Java// to //Scala//--yet it is not the usual style that is practiced.

In this space, I'll document my explorations into functional programming.  Most of the code here will be in either Java or Scala, though currently I'm using Java most of the time.

In this space I index my writings on functional programming, and particularly on Monads.
