[EBOOK] 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.

What’s inside
Patterns for simpler code
Powerful time modeling approaches to simplify asynchronous code
How higher-order functions can make code reusable and composable
