Grokking Simplicity: Taming complex software with functional thinking

Grokking Simplicity is a friendly, practical guide that will change the way you approach software design and development.

Summary

Distributed across servers, difficult to test, and resistant to modification-modern software is complex. 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.

About the technology

Developers rightly fear the unintended complexity that infects most code. This book shows you how to write software that keeps complexity close to its inherent minimum. As you write software you should distinguish between code that alters your system's state, and code that does not.
