Module
Noun · Development
Definitions
A self-contained unit of code — typically a file or package — that encapsulates related functionality and exposes a defined interface for other parts of the program to use.
In plain English: A separate file or package of code that handles one specific job and can be imported wherever it's needed.
Example: "Break it into modules. A 5,000-line file is not a module, it's a cry for help."
