New article: Elixir Public vs Private Functions
I’ve published the next article in my Elixir learning series on dev.to, exploring private vs public functions — what defp actually protects, and how a small public surface keeps a module easy to change.
What it covers
defvsdefp, and how the compiler enforces that boundary- Refactoring our todo modules: turning inline steps into private helpers and simplifying return shapes
@docon private functions vs@doc false— and reading a module’s surface with__info__- Patterns that show up constantly: public wrapper / private engine, private edge cases, and a recursive worker
It keeps building on the same learning_elixir Mix project — every example is a real file you can copy and run with mix run.
