The functional approach to programming Guy Cousineau

Ben Nadel compares ColdFusion query-of-queries to a functional programming approach to collection-based CRUD (Create, Read, Update, Delete) operations. For well over a year, John Liao's Blog has been tackling chapters from my WPF book Applications = Code + Markup and converting the code into F#, the functional programming language developed at Microsoft. The book assumes no prior knowledge of Haskell or functional programming. F# inventor Don Syme has provided a convenient guide to John Liao's Guy Cousineau's (co-author of "The Functional Approach to Programming"), "Tiling as a programming exercise". It starts off with simple, introductory topics and explains concepts of functional approach to programming. Sometimes functional approaches are best, sometimes imperitive and OO programming paradigms are called for. 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. Maybe I've not learned enough about functional programming, but it doesn't seem functional to me. The functional programming is just on some higher level. 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. 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. I recorded a series of screencasts teaching concurrency to C++ programmers. 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. Though Delphi is definitely an imperative language, the second code snippet is an example of functional approach to programming. However, I thought this was an imperative approach to coding? Yes, you can solve this by putting every field inside an IORef, but then you can't apply pure processing functions to the structure anymore, so you loose the functional approach. Now let me insert my commercial: I don't think that's good programming practice.
