Detecting copy and paste in JavaScript is not something that’s new to web development. How you do it may vary, though, depending on the set of tools you’re using.

Cut and paste, not cut and tape. And not like this.
Given I focus primarily on WordPress, the majority of the JavaScript I write uses jQuery. And though there are a number of ways you can go about doing this (which I’ll talk about later), some of them are deprecated (though they still work).
Anyway, so I was specifically looking for a way to handle the case where a user pastes content into a field using keyboard shortcuts.
