Treating Errors as Data
Explore how to handle errors in Elixir by converting exceptions into data structures, allowing pipelines to maintain context and manage failures effectively. Understand strategies for isolating state and error handling using GenServer, improving the robustness of your functional programs.

Common errors
Functional programs are simpler when we can use pipelines to simplify code. Transforming data is one of the fundamental tenets of Elixir. However, specific problems can arise.
Exceptions
Functions that fail often raise exceptions. When we don’t handle errors, they transition to code execution in the form of exceptions. Exceptions don’t compose neatly, and the resulting error codes aren’t always informative. ...
