FAQs about JavaScript Callbacks

A callback function is a function passed as an argument to another function, allowing it to be executed after the completion of a task.
Callbacks can be both synchronous (e.g., in array methods) and asynchronous (e.g., in API calls or event handling).
Callbacks enable the execution of other code while waiting for a task to complete, keeping the application responsive.
Callback hell refers to deeply nested callbacks that make code hard to read and maintain. It can be avoided using promises or async/await.
Yes, a callback function can return a value, but it is typically used to pass data to another function.
