How to improve your JavaScript programs using functional techniques

Look inside

read excerpt

about the technology

In complex web applications, the low-level details of your JavaScript code can obscure the workings of the system as a whole. As a coding style, functional programming (FP) promotes loosely coupled relationships among the components of your application, making the big picture easier to design, communicate, and maintain.

about the book

Functional Programming in JavaScript teaches you techniques to improve your web applications: their extensibility, modularity, reusability, and testability, as well as their performance. This easy-to-read book uses concrete examples and clear explanations to show you how to use functional programming in real life. If you're new to functional programming, you'll appreciate this guide's many insightful comparisons to imperative or object-oriented programming that help you understand functional design. By the end, you'll think about application design in a fresh new way, and you may even grow to appreciate monads!

what's inside

• High-value FP techniques for real-world uses
• Using FP where it makes the most sense
• Separating the logic of your system from implementation details
• FP-style error handling, testing, and debugging
• All code samples use JavaScript ES6 (ES 2015)

about the reader

Written for developers with a solid grasp of JavaScript fundamentals and web application design.

This book transformed the way that I think about and write JavaScript.

Easy to navigate, with real-life examples.

Now, this is the way to write JavaScript!

After reading this book, I revisited how I approached coding and was able to retrain my mind using better methods and techniques.
