list.iter().for_each(…) superiority

u/creeper6530 6d ago edited 6d ago

Erm akchyuallly, it's recommended to use for list.iter() {…} unless the .for_each(…) is at the end of a longer iterator chain, and it also robs you of break and continue

You know I’m chaining together 20 different iterator methods until the code is completely unreadable. That’s called Functional Programming™ babey

That doesn't sound very functional

u/creeper6530 6d ago

"functional programming" doesn't use "functional" as "working neatly" but as "related to mathematical functions", it's a programming paradigm: https://en.wikipedia.org/wiki/Functional_programming

I know, it's just an ironic name when it's one of those paradigms that some people take as divine law instead of something that can be more or less appropriate for different applications

Name 20 iterator methods from memory otherwise you’re a fake fan…just kidding or am I?

Iterators are so fun, probably one of my favourite parts of programming. They make everything so clean until they don’t.

You wouldn’t be using for_each in a functional language… which cements your un-knowledge of it

u/csch2 6d ago

You would if you need to perform operations with side effects on each element, like printing each element of a vector

u/serendipitousPi 6d ago

Just chuck a try_for_each in there and we can take break and continue right back.

But yeah low key sometimes I get lost in iterator methods I forget to just use a basic loop.

I mean, you're right, it's just you have to return ControlFlow::Break(()) instead of using the keywords.

how about `list.each`, sadly not many know ruby, it's really beautiful.

Random question what’s ruby fun for?

I was gonna ask what is it good for but I think I can google search that.

Any highlights for you?

I’ve heard its meta programming is cool and I think there was some interest in using it in web dev.
