Is there the difference between jump you and jump at you? I am asking since I see the same translation of them from the context.
She looked at him, scowling with an anxiety she did not like to admit
to herself, at the fresh rips in the knees of his blue jeans, the
streaks of dirt grained deep in his shirt, a darkening bruise on the
cheekbone under his left eye. “Okay, did the big boys jump you in the
schoolyard this time, or when you got off the bus?”

"Jump you" Is a slang term, and it essentially means the same thing as "Ambush", or to attack a person when they weren't expecting to be attacked. It is frequently used when someone attacks you to steal something. Source
"Jump at you" is not as much of a slang word. It means to jump in your direction. However, even though it's not a slang word, it is frequently used metaphorically.
For something to "jump out at you" might mean that you noticed it instantly as though it was jumping up and down and everything else was still. Source
To "Jump at something" can mean to try to approach or obtain it as fast as you can. It is as though you jumped out of your starting position in order to get to it instead of more leasurly approaching it. Source
