Takaisinkutsut
Takaisinkutsut (callbacks) are a programming pattern in which a function is passed as an argument to another function and is invoked later, often in response to an event, completion of an asynchronous task, or user action. The passed function is called back by the callee when the triggering condition occurs, allowing the caller to specify behavior to run at that moment without blocking.
In practice, callbacks are central to event-driven and asynchronous programming. Common use cases include handling user
Design considerations: callbacks enable non-blocking operations but can lead to deeply nested code, often referred to
Global usage: callbacks are widely used across programming languages, including JavaScript, Python (for asynchronous tasks or
