elevator pitch - 300 character
A functional programming background is certainly not required for Elixir but understanding a few functional principles can make your life easier and your code considerably more Elixir like.
public abstract
At first glance, Elixir looks a lot like Ruby but about 10 minutes of coding in Elixir will put a screeching halt to that idea. Erlang's functional/distributed programming background shines through in Elixir. Combined with a modern/familiar syntax and a great macro language Elixir gives us an ideal way to start down the functional programming path.
If I had to describe the Elixir Way in one word, it would be "explicit". Elixir avoids programming magic and instead strives for a clean, no surprises, style. We're going to look at a few functional concepts that help bring Explicit Elixir into perspective.
for reviewers
- code should tell a story
- pipelines
- pure functions
- small
- user more pattern matching,
- if a param needs to be something, pattern match and/or guard it
- use more map/reduce,
- for isn't as awful in elixir and gets rewritten as map
- if can get smelly quickly
- very short things only
- no new variables or assignment
- treat as expression that returns a value
- just avoid unless
- use with [maybe/maybe not, depends on time/example]
- refactor nested case
params that must/should be a thing, should specify that thing

- choose accurate names
- favor beauty over performance
- design minimal essential API's
- document the unobvious
