Does it matter that a blog post about an advanced Haskell topic isn't understandable by people who don't know basic Haskell? You wouldn't fault a calculus textbook for being incomprehensible to someone who doesn't know algebra. How is this any different than that?

I think it depends on your intended audience. For instance, I’m coming from a TypeScript-heavy background and:

1. I fully understood almost everything in this post, which I seldom do with typical Haskell writing, but

2. I’m also interested in Haskell, but find that level of required knowledge both off-putting and interest-reducing, and

3. This article could have completely left out TypeScript examples and still been just as informative and interesting for me, because the author cared to explain it to an audience with minimal Haskell background knowledge.
