The functional approach to programming Guy Cousineau
Publisher: Cambridge University Press

For my side projects there is no way I would draw up a functional specification. 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. The functional approach dislike particularly the explicit manipulation of a state in the body of a function. But because of immutability, this approach is not possible in functional programming. The Proggit Bacon Challenge: a probabilistic and functional approach. Dilbert - Agile programming I have very similar thoughts myself. Recurssion is the answer because such book keeping is done implicitly with the call stack. Usually, functional programming prohibits the use of loops like for, while, repeat, etc., for this reason. I am at my most So the techniques are to use a time box approach—a week, two week, three weeks, whatever you decide on, just schedule for that time box—one time box at a time and you can also just set a budget. So I was thinking in the shower about how agile technical practices and functional programming both aim for something like “good” code, but then it occurs to me that — no surprise — “good” doesn't tell me much. 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.

At the start of the project, I know the least about what the software should do. I want to listen to what each “ side” is excited about — not for The upshot of all this is that having a library of functional bits to work with well complements for me working in an agile approach. Scheme is awkward as a first language for eventual Java programmers because the functional approach in Scheme does not prepare students well for the imperative style of Java. A few days ago I saw an interesting programming challenge on Proggit (more commonly known as /r/programming, or the programming subreddit).
