How to teach functional programming? What are the proper steps, beyond the first ones? Especially when you can't or don't want to point to a framework and say "we do it this way!"

Lars outlines his ideas for teaching Elixir to someone without requiring any prior programming experience.

There is also discussion of mapping, reducing, and representing one in terms of the other. Also things which are better in Haskell than Elixir, perfectly named modules, and - inevitably - why you don't just use Rust instead.

Quotes

It felt like I cheated, I don't know if I did
In my bone marrow!
Putting the module before the functions
Try to explain a monad (there is no second step)
Pretend that the rest of computing doesn't exist
Ignore the rest of the world
Save brain cycles
Solid, sound, and true
It's going to have to be a reduce
I never really updated my map
