Would there be any benefit of only updating state when the user clicks the "save" button?

Does updating the App State on every change of the input have any performance impact? How would this solution be different if we followed this pattern?

Sensing only the button would be more conservative of the CPU resource, but when a browser is waiting on user interaction it generally has nothing else to do, so it would make no detectable difference in performance to the user.
