Discover Functional JavaScript was named one of the best new Functional Programming books by BookAuthority!

“發現功能JavaScript”被BookAuthority評為最佳新功能編程書籍之一 ！

Code is a way to communicate with developers reading it. Functions with intention-revealing names are easier to read. We read the function name and can understand its purpose. The function name is our tool for expressing intent on a piece of code.

代碼是與閱讀代碼的開發人員進行交流的一種方式。 具有意圖揭示名稱的功能更易于閱讀。 我們閱讀了函數名稱，并可以理解其用途。 函數名稱是我們表達代碼意圖的工具。

Let’s look at a list of operations done in a functional style with the use of anonymous functions.

讓我們看一下使用匿名函數以功能樣式完成的操作的列表 。

function getTodos(users){return todos.filter(todo => !todo.completed && todo.type === "RE").map(todo => ({title : todo.title,userName : users[todo.userId].name})).sort((todo1, todo2) => todo1.userName.localeCompare(todo2.userName)); }

Now check the same functionality refactored using functions with intention-revealing names.

現在，檢查使用具有意圖公開名稱的功能重構的相同功能。

function isTopPriority(todo){return !todo.completed && todo.type === "RE"; }function ascByUserName(todo1, todo2){return todo1.userName.localeCompare(todo2.userName); }function getTodos(users){function toViewModel(todo){return {title : todo.title,userName : users[todo.userId].name}}return todos.filter(isTopPriority).map(toViewModel).sort(ascByUserName); }

Function names give clarity to the code. With a good function name, you just have to read the name — you don’t need to analyze its code to understand what it does.

函數名稱使代碼更清晰。 有了一個好的函數名，您只需要閱讀名稱即可—您無需分析其代碼即可了解其功能。

It’s widely estimated that developers spend 70% of code maintenance time on reading to understand it.

據廣泛估計，開發人員將70％的代碼維護時間用于閱讀以理解它。
