I liked this book as an introduction to functional programming without it being overwhelming.

FP adherents often skip over the reasoning behind the tools and methods they use, which makes it hard for new folks to understand why they are using these unfamiliar abstractions.

Grokking Simplicity runs through a series of scenarios that illustrate the value in FP thinking and architecture. Read it from start to finish and you’ll be in a good spot to take FP into your day-to-day.

Downsides of the book are that it’s painfully slow sometimes (so just skim over the stuff you already know), and the choice of JavaScript as the example language. JS may be accessible to many readers, but the warts of the language show through and in some cases steal the show from the core FP concepts being expressed.

Overall I highly recommend this book, and I actually read and enjoyed the whole thing!

If the examples were in Clojure, and perhaps if the book were a bit more concise, it’d be a complete slam dunk. ( )
