For me, it’s the functional programming. Elixir is not the first functional programming I learn. But it’s the first functional programming I learn by doing, not just by reading the books. Another things are like pattern matching, pipe operator, recursive call, etc.

I think Elixir may actually make it slightly more confusing because a lot of folks coming from other language expect
'foo' == "foo". That’s why one of the proposals I want to send after v1.3 is out is to deprecate the use of'foo'in the long-term (and I really mean long-term) in favor of the sigil~c"foo". It is going to be more explicit and I find using sigils for char lists in Elixir at this point more idiomatic.gregvaughn
erlang charlists. Newbie exercises are bound to create a list of integers and iex will print it out in a surprising way. It’s a fundamental ambiguity that’s completely understandable, but it introduces itself to newcomers in a very surprising way.

For me so far syntax for piping into anonymous function was a bit surprising:
|> (&(&1)).()
