What's the difference between a promise and a callback in Javascript?
Can you explain the difference between a promise and a callback in Javascript?
Of course! In Javascript, callbacks and promises are both used to handle asynchronous operations. A callback is a function that is passed as an argument to another function and is executed when the first function is done, while a promise is an object that represents the eventual completion or failure of an asynchronous operation and can be used to handle callbacks.
