Learn javascript callbacks in 7 minutes

javascript callbacks are functions passed as arguments to other functions, executed after a certain task is completed. this concept is fundamental in asynchronous programming, allowing developers to manage tasks like data fetching and event handling without blocking the main execution thread. callbacks enable a more efficient and responsive user experience, as they facilitate operations such as making api requests and handling user inputs. understanding callbacks is crucial for mastering javascript, particularly when dealing with asynchronous operations, as they help structure code and improve readability. however, they can lead to challenges like "callback hell," where nested callbacks become difficult to manage. to mitigate this, developers often use promises and async/await syntax, which provide cleaner and more manageable alternatives. overall, mastering callbacks is essential for any javascript developer, as they form the foundation for handling asynchronous behavior and enhancing application performance.
