Introduction In this post we will discuss the concept of fold in functional programming: fold functions are used to reduce a data structure containing multiple values into a single one. Associated to the idea of fold are the concepts of recursion: via recursion, fold traverses the different elements of the data structure. summarisation: the data …

This post presents some features of functional programming with Scala. In essence, functional programming is about programming by making use of mathematical functions. All well-known features of functional programming are just a result of using mathematical functions, e.g.: referential transparency immutable state higher-order functions pattern matching I especially like ‘pattern matching’ as it allows for a …
Background This post describes my experience playing around with Scala and some of its concepts like tail recursion and futures. It also offers an opportunity to see how a memory leak can happen and how to analyse it. I created a simple web crawler that takes a seed link (e.g. http://www.bbc.co.uk) and then, recursively (using tail recursion), collects all …
