What does "loose coupling" mean in programming?
loose coupling 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 goal where modules interact through stable, minimal interfaces and know as little as possible about each other's internals. Loose coupling makes it easy to swap, test, or modify one module without affecting others.
Example
"Event-based communication achieves loose coupling — the publisher does not know or care who listens."
