Answer
Effects handle side effects like API calls, caching, and async workflows without polluting reducers. They keep the store pure and predictable.
Quick Answer
NgRx Effects handle async side effects (HTTP calls, navigation) triggered by actions. An Effect listens for specific actions, performs async work (HTTP request), and dispatches success or failure actions. Keeps side effects out of reducers (which must be pure functions) and components (which should only dispatch actions). Effects are testable, isolated, and handle complex async workflows cleanly.
