Why was this question about functional reactive programming closed? What is (functional) reactive programming?
I found it because it's the number 3 hit on Google for its topic. Sure, it's a niche topic, but that makes its nearly 36,000 views even more impressive. There are two highly rated answers from high-reputation users.
This isn't my question, nor are any of the answers. I just think there's no reason to close useful content based on a narrow interpretation of what's on or off topic.
