Why do we use "else if" and not "else"?

The use of else if is to limit when the code will run.

The event handler will be invoked for any button, but the if and else if are used to run code only on the "remove" and the "edit" buttons. If the "else if" were replaced with "else", then the code intended for the the "edit" button would run when any button other than "remove" was clicked.

This might not seem important if there are only those two button types in the list, but it could cause big trouble in the future if another button type was added to the list.

It ends up being easier to maintain and lets say the client wants to add additional buttons, would be much easier of a feature to implement if their is a method like the conditional checks applied using else if vs only checking one condition with else.

Thanks Steven,

but if I should have only two buttons does it make sense to use "else" instead of "else if"? What you say is valid only if in the future i should add other buttons, isn't it?
