THE BOOLEAN TRAP

Summary from the TLDR Web Dev newsletter

Using boolean flags in function parameters is a trap - enums should probably be used instead. Boolean flags can lead to confusion and maintenance issues, especially when dealing with multiple output types. While boolean flags can be appropriate in specific cases, enums are generally preferable for API and function parameters because they are more readable, maintainable, extensible, and future-proof.
