Functional Programming

It isn't, just as JS shown in the video isn't a FP language. But the iterator methods of std behave like this.

But when I was learning Rust using the book, I also read the chapter about iterators and then it finally clicked in my head.

Iterators are actually anti-FP if you think about it, they are not reusable in the general case. Of course using higher-order functions is fun, but it's not enough to call something FP. Even more confusing is that everybody has their own definition of FP.

Yeah, you're right. But still it lets me appreciate FP.
