Grokking Simplicity (Manning)

Grokking Simplicity is a friendly, practical guide that will change the way you approach software design and development. It introduces a unique approach to functional programming that explains why certain features of software are prone to complexity, and teaches you the functional techniques you can use to simplify these systems so that they’re easier to test and debug.

Eric Normand

As you write software you should distinguish between code that alters your system’s state, and code that does not. Once you learn to make that distinction, you can refactor much of your state-altering “actions” into stateless “calculations.” Your software will be simpler.

The book also teaches you to solve the complex timing bugs that inevitably creep into asynchronous and multithreaded code. In ad­vanced sections of the book you learn how composable abstractions help avoid repeating code and open up new levels of expressivity.

Sounds like a very difficult book to write :open_mouth:

Eric currently offers a discount code for 50% off; it’s right at the top of PurelyFunctional.tv, his Clojure training site.

After seeing the subtitle, it made a lot of sense. Almost every time I try to apply a functional approach, instead of keeping state in some kind of object, it seems so much simpler to code – and to test.
