Small suggestion. Don't choose obscure language (in terms of popularity, 28th on TIOBE index with 0.65% rating) to visualize structure and algorithms. Otherwise you risk average viewer will stop reading the moment he encounter code samples. There are 27 more popular languages, some of them orders of magnitute more.

Maybe he doesn’t care if people stop reading and he’d prefer to use the language he’s most comfortable with? It’s his blog after all, not yours.

Additionally, perhaps he’s making the point that a language with an expressive type system makes solving problems like this trivial.

If you don't care about readers reading it or not then what is the point to publish an article ?

[louthy]

I read it. Probably lots of other people did too. Presumably the people who don’t think computer science begins and ends with JavaScript

Why does there have to be a point? If there is one, why do you need to understand it?

[daaaaaaan]

I appreciated the Haskell examples, they aren't particularly hard to follow. How do you think those more popular languages got more popular?

The code is a relatively small part of the article, and quite far into it I might add.
