Edit3: Even though I would like to find this video, I am mainly looking for educational material on recursion and pattern matching in elixir. If you think you have a good source, please post, even if it is not what I am looking for!

I watched a talk on YouTube when I was still pretty new to elixir (2 years ago? 3? Time flies) and I just don’t know how to find it again.

As far as I remember, the presenter was a man, maybe in his 50s, with a dad-body, talking about how he started using elixir and Phoenix, doing everything wrong and coming back to it, when finally pattern matching and recursion “clicked” for him.
He presents a very basic example of recursive functions, starting with something like def my_func([a | rest], acc) and ending with “what is your exit condition?”

The slides were literally the code going through the iterations, and it was a pretty good production.

This talk was basically what made recursion and pattern matching click for me, I would like to share it - but I just can’t find it… Please help.

Edit: one specific thing I remember is the presenter mentioning using elixir (Phoenix) without understanding recursion and how he made it work, but in a horrible way.

Edit2: I am looking for a specific video, but I already got some great suggestions! Even if it’s not what I’m looking for, this is fantastic. Keep it coming
