On @AstonJ ’s suggestion, I decided to start a thread on recursion. It’s one of my biggest mental hurdles to get over while learning FP. (My OOP brain just wants to iterate through everything.) I’ve scoured the Internet for good resources on recursion, but I’ve come up empty. So far, I’ve seen sugge…

How far through the book are you? This might help us get an idea of which bits you have covered.

These online books on functional programming are good resources to learn FP concepts and recursion: Learn You Some Erlang - Recursion Learn You A Haskell - Recursion Clojure for the Brave and True - Living with Immutable Data Structures I hope that helps!

I’m currently in the middle of Chapter 10, which is the Enumerables section.

Actually, I don’t think recursion is hard, It’s quite easy if you’re familiar with C. Example in C: #include <stdio.h> void recurse ( int count ) /* Each call gets its own copy of count */ { printf( "%d\n", count ); if (count <= 0) return; recurse ( count - 1 ); } int main(int argc, c…

[image] detectivemittens: Do you guys have any tips on how to think recursively? For Elixir it is a little bit harder than other languages. But the first thing you need to realise is, that recursion is just the natural way to define loops in functional languages. Also, for datatypes which ar…

[image] detectivemittens: Do you guys have any tips on how to think recursively? When writing recursive functions, first I try to think about stop condition, i.e. when I need to stop execution and return the result. Also I try to think of all different states function’s argument might have, …

I do not miss it in imperative languages. I use it. Ok I do not have nice multihead functions, but I use similar recursion patterns as in functional languages. Most of the time the functions are easier to read than their counterparts with classic loops.
