is "this" in JavaScript prototypes, what "this" in jQuery is built on?

:point_right: The function of this is built into JavaScript.

It doesn't matter if you are using JQuery or not, the meaning of this is determined by context in which it is used. For examples, inside an object method it will be the object itself, or inside an event handler it will be the element that triggered the event.

Thanks, I pretty much get that part. I was thinking if you looked behind the scenes of a jQuery $(this) would you see some conglomeration of JS prototypes. Cause up until prototypes, I haven't seen "this" in JS, that I can recall anyway.
