🔗 Learning Elixir: tuples

Tuples are like standardized forms where each field has a fixed position and specific meaning. In a user registration form, the first field is always the type (:user), the second is the ID, the third is the name, and the fourth is the email. You can't add extra fields or change the order - the structure is fixed and each position has its well-defined purpose. Think of {:user, 123, "Alice", "alice@example.com"} as a structured record where each position tells a specific part of the story. Once created, tuples keep their size and elements in their exact positions, making them perfect for structured data where order and position matter. In this article, we'll explore how tuples work, when to use them, and the patterns that make them indispensable in Elixir programming.

Note: The examples in this article use Elixir 1.18.3. While most operations should work across different versions, some functionality might vary.
