Functional architecture is Ports and Adapters
Functional architecture is Ports and Adapters by Mark Seemann Functional architecture tends to fall into a pit of success that looks a lot like Ports and Adapters. In object-oriented architecture, we often struggle towards the ideal of the Ports and Adapters architecture, although we often call it something else: layered architecture, onion architecture, hexagonal architecture, and so on.

Operator Glossary
One aspect of Haskell that many new users find difficult to get a handle on is operators. Unlike many other languages, Haskell gives a lot of flexibility to developers to define custom operators. This can lead to shorter, more elegant code in many cases. For example, compare these three equivalent pieces of code: v1 = mappend (mappend "hello " "there ") "world" v2 = "hello " `mappend` "there " `ma

Lenses
Haskell's Lens type generalizes properties (i.e. accessors/mutators) found in other programming languages. For example, C# provides language support to treat properties as ordinary variables: class Point { public double x { get; set; } public double y { get; set; } } class Circle { public Point center { get; set; } public double radius { get; set; } } public void goRight(ref Circle c) { c.center.x
