Answer
Dependency Injection provides required services to components automatically.
It improves testability, reduces coupling, and organizes application logic.
Quick Answer
Angular DI is a design pattern where services (dependencies) are provided to components/services that need them rather than created inside them. Angular's injector creates and caches service instances. Declare services with @Injectable, register them in providers, and inject via constructor parameters. DI enables loose coupling, testability, and service sharing across components.
