Mastering Functional JavaScript Programming

Key FeaturesLearn what functional programming is, why it's effective, and how it's used in JavaScriptSuccessfully apply Functional Programming concepts and techniques to everyday JavaScript programmingBring modularity, reusability, testability, and performance to your web appsBook DescriptionFunctional programming is a programming paradigm for developing software using functions. Learning to use functional programming is a good way write more concise code, with greater concurrency and performance. JavaScript is a language that is particularly suited to functional programming.This book provides comprehensive coverage of the major topics in functional programming with JavaScript to get shorter, clearer, and testable programs.You’ll dive deep into functional programming; writing and testing pure functions, reducing side effects, and other features to make your applications functional in nature.Specifically, we’ll explore techniques to simplify coding, apply recursion for loopless coding, learn ways to achieve immutability, implement design patterns, and work with data types.By the end of this book, you’ll have developed the JavaScript skills you need to program functional applications with confidence.What you will learnCreate more reliable code with closures and immutable dataConvert existing methods into pure functions, and loops into recursive methodsDevelop more powerful applications with currying and function compositionSeparate the logic of your system from implementation detailsImplement composition and chaining techniques to simplify codingUse functional programming techniques where it makes the most senseAbout the AuthorFederico Kereki is a Uruguayan Systems Engineer, with a Masters Degree in Education, and more than thirty years’ experience as a consultant, system developer, university professor, and writer.He is currently a Subject Matter Expert at Globant, where he gets to use a good mixture of development frameworks, programming tools, operating systems, such as JavaScript, Node.JS, React + Redux, SOA, Containers, and PHP, with both Windows and Linux.He has taught several computer science courses at Universidad de la República, Universidad ORT Uruguay, and Universidad de la Empresa, for whose courses he has written some texts.He has written several articles—on JavaScript, web development, and open source topics—for magazines such as Linux Journal and LinuxPro Magazine in the United States, Linux+ and Mundo Linux in Europe, and for web sites such as linux and IBM Developer Works. He also wrote booklets on computer security (“Linux in the Time of Malware” and “SSH: A Modern Lock for your Server”) and a book (“Essential GWT: Building for the Web with Google Web Toolkit”) on GWT programming.Kereki gave talks on Functional Programming with JavaScript in public conferences (such as JSCONF 2016) and has used these techniques to develop Internet systems for businesses in Uruguay and abroad.His current interests tend toward software quality and software engineering— with Agile Methodologies topmost—while on the practical side he is working with diverse languages, tools, and frameworks, and Open Source Software (FLOSS) wherever possible!He usually resides, works, and teaches in Uruguay, but he is currently on a project in India, and he wrote this book in that country.
