+# Expose Internal Representation
+
+Elixir is a language that has strong support for metaprogramming. It
+provides easy access to an internal representation of the code in the form
+of an Abstract Syntax Tree (AST) using maps and keyword lists. The `quote`
+function is used to expose this internal representation.
+
+```elixir
+> quote do: 2 * 2
+{:*, [context: Elixir, import: Kernel], [2, 2]}
+> quote do: 2 * 2 == 4
+{:==, [context: Elixir, import: Kernel],
+ [{:*, [context: Elixir, import: Kernel], [2, 2]}, 4]}
+```
