反应式和功能反应式编程之间的区别 [英] The difference between Reactive and Functional-Reactive programming

问题描述

最近我一直在研究反应式编程，我发现很难找到Reactive和 Functional -Reactive之间区别的很好描述。

简单地说，反应式编程是使用函数方法/范式实现的，而不是使用声明式或OO范式？

解决方案

功能反应规划（FRP）是一种具有特定语义的特定编程模型。
（实际上，有两种变体，有时称为经典FRP和箭头FRP。）
我在正如我在那里所说的那样，对我来说这两个关键属性一直是（a）精确&简单的外延和（b）连续的时间。
我很遗憾这种模式被称为功能性反应式编程，原因如下：

• 该名称省略了时间，时间对我来说是至关重要的。


• 术语功能具有很少的特定/明确含义。
  我更喜欢Peter Landin建议的替代外延。
  （参见本博客评论）


• 人们很容易错误地认为他们知道这个词的含义，因为他们知道每个词的含义（或多或少）。

有关描述性和放大功能，准确性，我更喜欢术语外延连续时间编程（Jake McArthur在谈话中提出的建议），而不是功能性反应性编程。 非常短篇幅的博客文章FRP的起源 功能性反应式编程中的早期灵感和新方向 。

I have been doing some research into reactive programming recently and I'm finding it hard to find a good description of the difference between Reactive and Functional-Reactive.

Is it simply that the reactive programming is implemented using functional methods/paradigms as opposed to using declarative or OO paradigms?

解决方案

Functional Reactive Programming (FRP) is a specific programming model with a specific semantics. (Actually, there are two variants, which are sometimes called "classic FRP" and "arrow FRP".) I've given a summary in an answer to "What is (functional) reactive programming?". As I said there, the two key properties for me have always been (a) precise & simple denotation and (b) continuous time. I regret that this model came to be called "functional reactive programming", for a few reasons:

• That name omits "time", and time is central for me.
• The term "functional" has so little specific/clear meaning. I much prefer Peter Landin's suggested replacement "denotative". (See the quotes and reference in this blog comment.)
• It's easy for people to incorrectly think they know what the term means because they know meanings (more or less) of each of the three words.

For descriptiveness & accuracy, I prefer the term "denotative continuous-time programming" (suggested by Jake McArthur in a conversation a while back) over "functional reactive programming".

I wrote a very short piece on the origin of FRP in the blog post Early inspirations and new directions in functional reactive programming.
