Deep dives
Understanding Elixir Macros
The podcast highlights the challenges new developers face when using Elixir macros, specifically with the usage of quote and unquote. Quote is used to convert Elixir code into an abstract syntax tree (AST), while unquote evaluates variables within that quoted context, creating potential confusion for beginners. To aid understanding, it is suggested to view a short video that breaks down these concepts, as macros can become complicated quickly when trying to determine whether to quote or unquote variables. The speakers share personal strategies, including their preference to avoid macros unless absolutely necessary, opting instead for direct function calls when possible.
