Here is how we write the famous factorial function as a Scheme program: (define (fact n) (if One of the advantages of the 'functional' approach adopted by Scheme is that most evaluations can be modeled as simple substitutions. With our previous approaches we had to explicitly code for handling the first file in ways that don't map trivially to changing your mind about which file you need, but with lists of promises it's easy. However, I thought this was an imperative approach to coding? Functional approach is interesting. Talking about the functional programming folks picking up Scala more and more, even Martin Odersky said this in his comment on one of such inflamatory posts .. Together with Phil Trelford, we're doing a tutorial called Turning to the Functional Side with F#. The present methods of determining the functional design of computers are critically reviewed and a new approach proposed. Maybe I've not learned enough about functional programming, but it doesn't seem functional to me. Great, so, I've got you interested in functional programming, now what the heck do you? It is described as such simply because functions are first-class values: many other features that define functional programming – immutable data, preference for recursion over looping, algebraic type systems, avoidance of side effects – are entirely absent. The concepts of expression and procedure lead directly to the use of a Polish string program. When trying to build a new capability within my team, my preferred approach is to identify a potential pioneer. Functional programming is becoming more and more mainstream these days. In what way is functional programming new and how can we use it? December 2nd, 2009 | Programming. C# 3.0, Python & Ruby have embodied many of the functional approaches.
