JavaScript Functional Programming Explained: Fusion & Transduction

###Introduction

Fusion and transduction may be the most practical tools I’ve picked up in my time studying Functional Programming. They’re not tools I use every day, nor are they strictly necessary, but, they completely changed the way I think about programming, modularity, and abstraction in software engineering, permanently, and for the better.

And to be clear, that’s really the point of this article: Not to evangelize FP, offer a silver bullet, or illuminate some magic secret sauce that’s “better” than what you do now. Rather, the point is to shed light on different ways of thinking about programming, and broaden your sense of possible solutions to everyday problems.

These aren’t easy techniques to use fluently, and it’ll probably take some time, tinkering, and deliberate practice to fully comprehend what’s going on here. For most, it’s an entirely new level of abstraction.

But, if you put in the time, you might just come out with the sharpest sense of abstractions around functions that you’ve ever had.
