Why do we putting parenthesis onclick calls the function instantly?

I don't get it why we did not put those parentheses on the On Click call.

Adding parentheses to a function name creates a call, which happens immediately. But when you provide a function as a callback, you don't want to call it now. Instead, you want to pass a reference to it so it can be called later.

And a function name by itself serves as a reference to the function without calling it.
