Composing Software An Exploration of Functional Programming and Object Composition in JavaScript

In "Composing Software", Eric Elliott shares the fundamentals of composition, including both function composition and object composition, and explores them in the context of jаvascript. The book covers the foundations of both functional programming and object oriented programming to help the reader better understand how to build and structure complex applications using simple building blocks.
You'll learn:Functional programmingObject compositionHow to work with composite data structuresClosuresHigher order functionsFunctors (e.g., array.map)Monads (e.g., promises)TransducersLensesAll of this in the context of jаvascript, the most used programming language in the world. But the learning doesn't stop at jаvascript. You'll be able to apply these lessons to any language. This book is about the timeless principles of software composition and its lessons will outlast the hot languages and frameworks of today. Unlike most programming books, this one may still be relevant 20 years from now.
This book began life as a popular blog post series that attracted hundreds of thousands of readers and influenced the way software is built at many high growth tech startups and top tech companies.
