Functional programming (函數式程式設計) 是一種已有六十年歷史的程式設計範式，為何現在變得越來越重要？這是因為隨著各種連網設備 (如行動裝置) 和雲端服務的普及，多程序透過網路交換訊息已成為常態，因此分散式系統的開發變得至關重要。分散式系統軟體開發的複雜性往往導致開發過程容易陷入混亂，程式碼盤根錯節難以除錯維護與擴展，成為揮之不去卻又不敢動的痛處。而 functional programming 的簡約風格因此受到廣泛關注。這種設計範式強調使用函式來構建應用程式，程式碼清晰又容易維護，亦能解決分散式系統多執行緒的問題。除了專門的函數式語言之外，Python、Java、JavaScript、C#、C++、Go 和 Rust 等知名語言的新版中，也因應趨勢增強了對 functional programming 的支援。只要建立了這種思維方式，你就可以應用在自己的程式語言中。市面上與 functional programming 相關的書籍 (主要為英文書) 通常由學者撰寫，內容偏重理論，而在大型實務專案經驗上顯得不足。這類書中的範例大多過於簡單，未能涉及實際軟體架構問題。與此相反，本書作者擁有二十年在產業界實際運用 functional programming 的經驗，從產業角度出發，旨在幫助那些在軟體工程實踐中遇到困難的工程師重新思考。即使你的目的不是分散式系統，學習 functional programming 的思維都能夠幫助你在撰寫任何程式時想得更周到。由於 functional programming 的特點 — 無 side effects（額外作用）和資料的不可變性 — 使得它非常適用於開發網路程式，在這種環境中，資料一致性和狀態管理是關鍵挑戰。本書透過 concurrency primitives（併發基本工具）實作、繪製時間線圖、分析並解決併發操作中的插緒問題，有效處理狀態變化和 bug，從而構建可靠的分散式系統程式。本書特色: ●作者從產業界的視角出發，旨在幫助那些陷入困境的軟體工程師，重新審視並採納 functional programming 程式設計方法。●為了更貼近軟體工程師的實際狀況，書中以廣泛熟知的 JavaScript 語言做示範。雖然 JavaScript 不是最理想的函數式語言，但這一點
