kódolásvisszahívás

kódolásvisszahívás translates to "coding callback" in English. It refers to a programming technique where a function is passed as an argument to another function, and the called function will execute the passed-in function at a later time, typically when a specific event occurs or a task is completed. This allows for asynchronous operations and event-driven programming, enabling programs to remain responsive while waiting for long-running processes.

In essence, a callback function is a piece of code that is "called back" by another part of the program. This is commonly seen in scenarios like handling user interface events (e.g., button clicks), asynchronous network requests, or timer functions. When the event happens, the callback function is executed, allowing the program to react accordingly.

The use of callbacks promotes modularity and flexibility in code design. It separates the execution of a task from the handling of its result. This pattern is fundamental in many programming paradigms and languages, particularly in JavaScript, where it's crucial for managing operations that don't complete immediately, preventing the program from freezing. Other common applications include asynchronous I/O operations and event listeners.
