哪个 JavaScript 库具有类似于 Haskell 的 do 表示法或 Scala 的 for 理解的功能？

Question

我正在探索一些用于函数式编程的 JavaScript 库，例如 Ramda、Sanctuary 等。我还检查了他们的管道和组合函数的链接和组合。但他们不能像下面这样同时使用 x 和 y 来产生最终值。

for {
    x <- xs
    y <- ys
} yield Point(x, y)

Sanctuary 和类似的库已经实现了单子数据类型。我想知道他们是否也支持诸如 do-notation 或 for-compression 之类的东西。可能他们已经有了，但我只是找不到该功能的正确名称。或者那些库有自己的方法来解决类似的问题。

基本上，我希望能够使用 do/for 之类的构造来删除结尾处的嵌套 flatMap 调用：

const S = require('sanctuary')

class Book {
    constructor(title, authors) {
        this.title = title
        this.authors = authors
    }
}

class Movie {
    constructor(title) {
        this.title = title
    }
}

const books = [new Book("FP in Scala", ["Chiusano", "Bjarnason"])
    , new Book("The Hobbit", ["Tolkien"])
    , new Book("Modern Java in Action", ["Urma", "Fusco", "Mycroft"])]

console.log(books)

console.log(books.map(b => b.title))

console.log(
    books.map(b => b.title)
        .filter(t => t.includes('Scala'))
        .length
)

function bookAdaptations(author) {
    if (author === "Tolkien") {
        return [new Movie("An Unexpected Journey")
            , new Movie("The Desolation of Smaug")]
    } else {
        return []
    }
}

console.log(bookAdaptations("Tolkien"))

console.log(
    books.flatMap(b => b.authors)
        .flatMap(a => bookAdaptations(a))
)


console.log(
    books.flatMap(book => (
        book.authors.flatMap(author => (
            bookAdaptations(author).map(movie =>
                `You may like ${movie.title}, `
                + `because you liked ${author}'s ${book.title}`
            )
        )
        )
    ))
)
