Front-of-the-Front-End and Back-of-the-Front-End Web Development
This honestly seems needlessly arbitrary.  If you’re the person whose job it is to write the component for a button making that button “work” (which almost always making a call to the backend and&#x2F;or loading up an additional component or making changes to the current one) is not anymore complex nor is it really a different skill set.  Front and backend makes sense as the two don’t even have to be the same language and front end is GUI work while backend is more number crunching, etc.  “back of the front end” and “front of the front end” doesn’t have anything close to the same kind of compartmentalization.  At least not in my experience.
