rebar3 shell

One of the things about rebar3 shell is that it does what you expect it to do with a project, whether small or large: it loads up the code paths, boots up applications (if specified to), allows a distributed node to run, lets you define custom scripts to prime its state, and lets you run rebar3 tasks within it, taking care of updating the state to work properly.

What make Elixir so attractive? Awesome collection.

• A natural syntax inspired by Ruby.
• Lazy evaluation from Haskell.
• Protocols, macros and pipelines from Clojure.
• Functional programming
• Extensibility
• Modern tooling
• Full compatibility with Erlang

Two types of string, why?

Elixir developers will mostly use the double-quoted representation，single quoted one exists mostly for backwards compatibility with Erlang — José Valim

The delightful char data

Char data lets you build up output strings by nesting lists, instead of constantly concatenating strings yourself. If you pass this value to a function that accepts char data, you never have to concatenate it yourself.
