Actually, you're wrong. This is bananas (based on very closely related FPR concept)

Secondly, you come off sounding defensive and ignorant. This is a new programming paradigm. Hopefully it will give people new ways to approach the same difficult problems. (And I really hope you believe GUIs are inherently difficult...)

No one is twisting your arm to learn FPR. If callbacks work for you in your job, then stick with what works.




When I was in college, and shortly afterward, I was very much into "new programming paradigms" and would get excited about lazy evaluation or continuations or whatever was the new cool idea going around. I have designed and implemented several programming languages built around new / wacky features; the most recent of these was ten years ago.

What you are hearing now is not ignorance, it is experience. I am a tremendously better programmer than I was in those days, and the way I got better was not by getting excited about wacky ideas; it was by really noticing what really works, and what doesn't; by noticing what are the real problems that I encounter in complicated programming projects, rather than what inexperienced / pundit / academic programmers tell me the problems are.

Clearly you didn't really read my comment, though, since you are saying "If callbacks work for you in your job..." and my entire point is that callbacks are terrible.


Also, no, I don't believe GUIs are inherently difficult. I do think most GUI libraries are just terrible though, because they have bought into bad GUI paradigms.

If a GUI is your example of something that is difficult, we are just living in different worlds and it's a challenge to have a productive conversation. I think a difficult task is something like "make this ambitious AAA game run on the PlayStation 3 performantly". That is pretty hard.


FRP isn't new. It is almost as olds as, or older than JavaScript
