Common Pitfalls for Elixir Developers

Tobias Pfeiffer, in their article '10 Elixir gotchas', addresses a variety of common traps that Elixir developers, especially beginners, may run into. These 'gotchas' range from unexpected behaviors of lists and numbers in interactive Elixir (iex), to confusion over charlists and strings, nuances in pattern matching with different data types, and peculiarities of Elixir's struct and map types. The author also touches upon keyword lists, term ordering when comparing different data types, as well as the behavior of nil values in specific scenarios. The post provides examples and explanations to clarify each topic, together with links to Elixir's documentation where these issues are acknowledged. Additionally, PragTob mentions a need for first-class constants in Elixir, as module attributes, the current solution, are limited in their scope and mutability. This article is full of practical insights for Elixir developers looking to deepen their understanding of the language and avoid common pitfalls.
