Elixir Language Maps and Keyword Lists
Syntax
- map = %{} // creates an empty map
- map = %{:a => 1, :b => 2} // creates a non-empty map
- list = [] // creates an empty list
- list = [{:a, 1}, {:b, 2}] // creates a non-empty keyword list
Remarks
Elixir provides two associative data structures: maps and keyword lists.
Maps are the Elixir key-value (also called dictionary or hash in other languages) type.
Keyword lists are tuples of key/value that associate a value to a certain key. They are generally used as options for a function call.
