JavaScript: Functional Programming for JavaScript Developers

About This Book

• Write powerful code with the high-level functions that JavaScript offers
• Discover what functional programming is, why it's effective, and how it's used in JavaScript
• Understand and optimize JavaScript's hidden potential as a true functional language

If you are a JavaScript developer interested in learning functional programming, looking for the quantum leap toward mastering the JavaScript language, or just want to become a better programmer in general, then this book is ideal for you. This guide is aimed at programmers, involved in developing reactive frontend apps, server-side apps that wrangle with reliability and concurrency, and everything in between.

• Get a run through of the basic JavaScript language constructs
• Code using the powerful object-oriented features in JavaScript
• Master DOM manipulation, cross-browser strategies, and ES6
• Understand the basic concurrency constructs in JavaScript and best performance strategies
• Harness the power of patterns for tasks ranging from application building to code testing
• Build large-scale apps seamlessly with the help of reactive patterns
• Explore advanced design patterns, including dependency injection
• Develop more powerful applications with currying and function composition
• Create more reliable code with closures and immutable data

JavaScript is a high-level, dynamic, untyped, lightweight, and interpreted programming language, and functional programming is a style that emphasizes and enables smarter code, minimizing complexity and increasing modularity.

This course will take you on a journey that shows how functional programming, when combined with other techniques, makes JavaScript programming more efficient. The first module stresses the practical aspects of JavaScript development, including everything that a modern JavaScript project will need.

The second module explores how design patterns can help you improve and organize your JavaScript code. You'll get to grips with creational, structural, and behavioral patterns as you discover how to put them to work in different scenarios.

The third module will help you to write real-world applications by utilizing a wide range of functional techniques and styles. It explores the core concepts of functional programming common to all functional languages, with examples of their use in JavaScript.
