This is fine but it's just a rehash of old well-knowned stuff. I don't see the value of learning this stuff one random blog post at a time. There are many books and established blogs with long series of material to give you an education.

Do you have an example of the many books and established blogs that you can share? A newcomer might not be familiar with where to start when attempting to learn more about functional programming.

  I'm a big fan of Haskell Programming from First Principles. That's where more advanced ideas like Monads started clicking. https://haskellbook.com/ https://haskellbook.com/

Known by you, maybe. None of these "affirmations" are common in any code base I work with, unfortunately.

It's a pretty good collection and summary of ideas I've only seen scattered around, before.

Could you list the top 5 ideas, with a short summary and a link to a well-regarded blog post that goes into more detail for each?

  ~~I can't tell if you're being sarcastic, but that's exactly what TFA does. But just to pull it out explicitly:~~ Edit: I think I misunderstood your point. You were asking for a similar kind of list as TFA from the other commenter which may not necessarily be the *same* 5 ideas Leaving the rest here in case it helps someone: 1.

    Yep, was kinda being sarcastic. IMO these sorts of posts are really valuable. They don't seem valuable when you're already familiar with the ideas and have read all the posts. But for people who are knew, they can really accelerate things. The comment kinda reminded me of the forum comments that will answer questions with "just use Google" and another person replies "I found this thread with Google ;(".
