• Web APIs (like setTimeout, fetch) handle asynchronous tasks and push callbacks to the callback queue once completed.

• The event loop continuou...read more

• Angular uses an injector to manage the creation and lifecycle of services.

• Example: A service can be injected into a component's constructor: constructor(private myService: MyService) {}
