Daily Term: Inversion of Control

Inversion of Control

Inversion of Control (IoC) is a design principle where the control of object creation and lifecycle is inverted from the application code to a framework or container. For example, in Spring (Java), a container manages object creation and injects dependencies, rather than the code creating them directly. IoC, often implemented via dependency injection, reduces coupling and improves modularity, but it can obscure control flow and make debugging harder.
