Callback function

This is a submission for DEV Computer Science Challenge v24.06.12: One Byte Explainer.

Explainer

Imagine you hire a helper (callback function) to do a task (your code). You tell them (call them) when you're done with your part (argument). They do their thing (execute), then let you know (return value) when they are finished.

Additional Context

The callback function helps to make code more concise and easier to understand by breaking complex tasks into simpler functions. When you call a function with a callback argument, you tell the main program to execute the callback function after it finishes its task. This way, your code becomes more organized and easier to follow.
