由Conal Elliott设计的推拉式玻璃钢

John Hughes将单子概括为箭头

Yes, but also no. According to Elliot, push is data driven FRP evaluation and pull relates to what is called "demand" driven evaluation. The author recommends pull because push tends to idle in between data inputs. Here's the crux: push-pull combines and balances these behaviors for the chief purpose of minimizing the need to recompute values. It's simple; operating FRP with push-pull hastens the ability to react. Arrow is a different technique for using abstract types to link values and evaluate them simultaneously. All these concepts are fundamentally different. But don't take my word for it: The nature of the Arrow interface is problematic for the goal of minimal re-evaluation. Input events and behaviors get combined into a single input, which then changes whenever any component changes, (Elliott). Thus, Arrow contradicts the goal of push-pull. That does not mean you can't use all of these at once, just that it would be complex, and there are some things you cannot compute without abstract Arrow types. I have not found scholarly opinions on which approaches are "the way of the future." Only note that arrows can handle simultaneity particularly well. If you could implement arrows and use push-pull to minimize computations, that would be the way of the future. Yes, they address separate purposes. As I said, they can be formulated together but it is difficult to implement and even if it does work, it would probably negate the reactive speed benefits of push-pull. That's subjective, but Reactive and Yampa appear to be the most commonly cited language libraries for FRP. I would say Reactive by Conal Elliott has deep roots, and Yampa is established as well. Other projects like Netwire arose as replacements, but it could be awhile before they replace the giants.

希望这能有所帮助!就像我说的，阅读我指出的文章会让你更好地理解箭头、推和拉之间的语义距离。
