This is the 13th post in the Exercises in Programming Style focus series. In this week in Exercises in Programming Style’s post, we will cover one of the foundation of Functional Programming, I/O. In Functional Programming, functions should be pure: a pure function’s return value must only depend on its input parameters.

This is the 12th post in the Exercises in Programming Style focus series. This week, we will focus on Aspect-Oriented Programming, a powerful programming technique: In computing, Aspect-Oriented Programming is a programming paradigm that aims to increase modularity by allowing the separation of cross-cutting concerns.

This is the 11th post in the Exercises in Programming Style focus series. This week’s post is dedicated to reflection: In computer science, reflection is the ability of a process to examine, introspect, and modify its own structure and behavior. The original Python solution is handled in different ways: the exec() function.

This is the 10th post in the Exercises in Programming Style focus series. In last week’s post, we solved the now familiar top-25-word-frequencies-in-a-text-file problem by using Event-Driven Programming. When the number of observer-subject pairs grows, an alternative is to migrate to the Event Bus. The Observer pattern is a messaging pattern: an Observer subscribes to a Subject. When the later emits an event, the former is notified.

This is the 9th post in the Exercises in Programming Style focus series. In the post from two weeks ago, we solved the problem using Object-Oriented Programming: we modeled the problem space using objects. For an object to communicate with another one, a dispatch() method was made available. Remember before the web was ubiquitous? Graphical user interfaces were already a thing.

This is the 8th post in the Exercises in Programming Style focus series. Last week’s post was dedicated to OOP. Despite popular belief, the exercise was solved using neither accessors i.e. getters and setters, nor shared mutable state. The solution’s implementation was based on traditional OOP constructs offered by the Kotlin language: classes, inheritance and overriding. Other languages may offer different ways to do OOP.
