Angular Services: Your App's Shared Toolbox

An Angular service is like a shared toolbox for your application. Instead of components building their own tools (like an HTTP client or logger), they request a single, shared instance from Angular's dependency injector. This keeps your code DRY and organized. Services are perfect for managing shared state, handling API calls, or centralizing business logic. The main footgun is manually creating `new Service()` inside a component, which defeats the purpose of a shared singleton and can lead to state management bugs.
