Callback: meaning, definitions and examples
๐ฅ๏ธ
callback
[ หkษหl.bรฆk ]
programming context
A callback is a function that is passed as an argument to another function and is executed after that function has completed. This concept is common in asynchronous programming, where a callback is used to handle the result of an operation once it is finished. Callbacks allow for code to be executed in response to certain events, thus enabling developers to create non-blocking I/O operations. They are prevalent in JavaScript, where functions like `setTimeout` and event handlers utilize callbacks extensively.
Synonyms
event listener, function reference, handler.
Examples of usage
- The function will call the provided callback once the data is loaded.
- Please provide a callback function to handle the response.
- In this example, the handleClick function is a callback.
- The API supports callbacks for improving performance.

Etymology
The term โcallbackโ originated in the field of computing and programming during the late 20th century when developers began to embrace structured programming paradigms. In the early stages of computer programming, functions began evolving from simple, sequential tasks into more complex operations, especially with the rise of event-driven programming. The term signifies the passing of control back to a piece of code after an operation is completed. This method gained major popularity with the development of web applications and environments such as Node.js, where asynchronous processing became essential for improving application responsiveness. Since then, callbacks have become a standard practice among programmers across various languages, allowing them to create responsive, interactive applications.
