I’ve published a new article in my Elixir learning series on dev.to exploring error handling with tagged tuples - the {:ok, value} / {:error, reason} pattern that’s idiomatic to Elixir.

The article covers:

• Understanding the tagged tuple convention and when to use it
• Returning descriptive results from your functions
• Handling errors at the call site with case and pattern matching
• Chaining operations cleanly with with and the else clause
• The bang convention (!) and its role in the ecosystem
• Practical patterns: validation, form handling, and batch processing

With complete working examples you can copy into IEx, you’ll learn how to treat errors as values and write code that handles failure paths explicitly.
