What does "composition" mean in programming?
composition is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
A design principle where complex behavior is built by combining simpler components, rather than through inheritance. 'Favor composition over inheritance' is a widely cited guideline from the Gang of Four design patterns book.
Example
"Instead of extending a base class, compose the object from smaller, focused components that can be swapped independently."
