Learning Functional Programming in Go: Function literals, Monads, Lazy evaluation, Currying, and more
Lex Sheehan begins slowly, using easy-to-understand illustrations and working Go code to teach core functional programming (FP) principles such as referential transparency, laziness, recursion, currying, and chaining continuations.
This book is a tutorial for programmers looking to learn FP and apply it to write better code. Lex guides readers from basic techniques to advanced topics in a logical, concise, and clear progression.
The book is divided into four modules. The first module explains the functional style of programming: pure functional programming, manipulating collections, and using higher-order functions. In the second module, you will learn design patterns that you can use to build FP-style applications. In the next module, you will learn FP techniques that you can use to improve your API signatures, increase performance, and build better cloud-native applications. The last module covers Category Theory, Functors, Monoids, Monads, Type classes and Generics.
- Learn how to compose reliable applications using high-order functions
- Explore techniques to eliminate side-effects using FP techniques such as currying
- Use first-class functions to implement pure functions
- Understand how to implement a lambda expression in Go
- Compose a working application using the decorator pattern
- Create faster programs using lazy evaluation
- Use Go concurrency constructs to compose a functionality pipeline
- Understand category theory and what it has to do with FP
By the end of the Learning Functional Programming in Go book, you will be adept at building applications the FP way.
