🔗 Learning Elixir: Error Handling with try/rescue/catch/after

Error handling in Elixir can be approached with two toolkits for different scenarios. try, catch, rescue, and after serve as a safety net for unexpected failures, while tagged tuples like {:ok, value} and {:error, reason} are for predictable issues. Elixir 1.20.1 introduces constructs that allow developers to handle exceptions like RuntimeError and ArgumentError. Understanding when to use these tools is essential since overusing them contradicts Elixir's philosophy of "let it crash." This article covers practical guidelines for implementing error handling effectively, demonstrating how to rescue exceptions, define custom error types, and clean up after errors gracefully.
