What is the lifecycle of services in Angular?

In Angular, services have a lifecycle that is tied to the injector that creates them. They can be created at different levels, such as root, module, or component level.

Can you explain the different levels where services can be provided?

Sure! Services can be provided at the root level, making them singleton across the application, or at the module or component level, where they are instantiated for that specific module or component.

What happens when a service is provided at the component level?

When a service is provided at the component level, a new instance of the service is created for that component and its children, allowing for isolated state management.

How can I manage the lifecycle of a service?

You can manage the lifecycle of a service by using Angular's dependency injection system, and by implementing lifecycle hooks like ngOnInit and ngOnDestroy in your service.
