I don't like the split between front and back end development. There are always some stuff that have to be done and are somewhere in between front and back-end, which developer will get to do it? Yes, there are differences definitely. Some don't like mingling with jQuery and other JS stuff. Some don't like Java or Python or whatever on the back-end is used. But some people do the whole thing, code from front-end to back-end and vice versa. They call themselves full stack developers.
