description: Functional Programming in JavaScript teaches JavaScript developers functional techniques that will improve extensibility modularity reusability testability and performance. Through concrete examples and jargon-free explanations this book teaches you how to apply functional programming to real-life development tasks. The book includes insightful comparisons to object-oriented or imperative programming which will allow you to ease into functional design. Moreover you'll learn a repertoire of techniques including function chaining and pipelining recursion currying binding functional composition lazy evaluation fluent error handling memoization and much more. By the end of the book you'll think about application design in a fresh new way.About the technologyAs web developers build increasingly complex applications in JavaScript the code base for these projects can become exponentially larger and harder to maintain. The result? Application performance suffers and readability and extensibility are severely compromised. For applications like these Functional Programming provides a saner approach allowing you to write elegant readable code that raises the level of abstraction while being less prone to errors. Although not a pure functional language JavaScript's native functional capabilities unlock access to proven functional programming techniques and practices.What's insideFoundations of functional programming and designExplore JavaScript's functional programming capabilities and the functional library ecosystemCreate more reliable code by embracing immutabilityLearn to write code that's easier to reason aboutSeparate core logic from program structure to write extensible codeAdopt a new approach to error handling and testingApply functional programming to solve real-world problemsAbout the readerReaders need to be comfortable with JavaScript programming and object-oriented design. No previous experience with functional programming is required.About the authorLuis Atencio is a Staff Software Engineer for Citrix Systems in Ft. Lauderdale FL.
