callbacks

A callback is a way to handle nearby tasks or responses in programming. Imagine you give a friend a list of errands with instructions on what to do after each task is completed. When your friend finishes, they call you back to report or continue the next step. In programming, a callback is a function passed into another function, which gets executed once a certain task finishes, like waiting for data from a server. This approach helps manage asynchronous operations efficiently, allowing programs to stay responsive and handle multiple tasks without waiting idly.
