=== Metaprogramming === Elixir provides a powerful metaprogramming capability through its macro system. Metaprogramming allows developers to write code that generates code, enabling advanced code transformation and code generation techniques. With metaprogramming, developers can extend the language itself and create domain-specific languages (DSLs) tailored to specific problem domains. Elixir macros, defined using the `defmacro` construct, are invoked at compile-time and they transform code before it gets executed. This enables developers to define higher-level abstractions and reduce boilerplate code. Elixir itself extensively uses metaprogramming in its standard library and popular frameworks like Phoenix.
