| ''Task'' - wraps a coroutine and schedules it to run on the event loop immediately (in the background). The task starts running as soon as the event loop gets a chance (e.g., when you next await something; await triggers an iteration of the event loop).\\ | ''Task'' - wraps a coroutine and schedules it to run on the event loop immediately (in the background).
