Empty function

An empty function is like having a blank piece of paper. You can write anything you want on it, but if you choose not to write anything, then the paper stays blank. In computer programming, an empty function is a function that doesn't have any instructions or commands written in it. It's like having a container that has nothing inside. It's there, it exists, but it doesn't "do" anything until something is put into it. Similarly, an empty function is like a container that can hold commands, but if none are put into it, then the function doesn't do anything. It's used as a placeholder, to be filled with code later on. So it's just like having an empty box that you can choose to fill up with whatever you want at a later time.
