I am an absolute fan of pipeline-oriented programming. In this article I want to show you a few ways in which Scala makes this way of working very natural, and then see how we can mimic a fraction of that power in PHP. Enter Scala I wrote a program that

Last time, we created a testable implementation of a simple function, that takes an order, computes some values like net / gross totals and tax, and returns the result so we can print it. Here is part 1 if you're interested. As a refresher, here is what that program

In this article I want to show you how to increase function purity, modularity and testability in inherently impure programs, based on a realistic code example. 🤠The following code snippets are not necessarily best practices. Each snippet is supposed to highlight one specific characteristic, without mixing in too many concepts

A common task I face when programming is to store multi-line strings in a variable. This may be related to templating for views, emails or configuration files for third party systems, or just writing readable inputs for tests. The naive approach First I want to show you the naive approach:
