Composable Function

Definitions

1. A function designed so its output or behavior can be cleanly combined with other functions to build larger behaviors without tight coupling. Composable functions usually have clear inputs, limited side effects, and predictable return values that make them easy to chain or reuse.

   In plain English: A function that is easy to combine with other functions to build larger behavior.

   Example: "The refactor broke the giant formatter into small composable functions so parsing, normalization, and rendering could be tested separately and recombined as needed."
