Preface

When I was in college and graduate school, my class schedule was focused on object-oriented design as the sole methodology for planning and architecting software systems. And, like many developers, I began my career writing object-oriented code and building entire systems based on this paradigm.

Throughout my development career, I’ve learned and followed programming languages closely, not only because I want to learn something cool, but also because I’m intrigued by the design decisions and philosophy that each language fosters. Just as a new language provides a different perspective on how to approach software problems, a new paradigm can achieve the same effect. Although the object-oriented approach continues to be the modus operandi of software design, learning about functional programming will open your eyes to new techniques that you can use on their own or in parallel with any other design paradigm that fits your application.
