If you took a time machine back in time, along with the source code for Jquery. In what year would you not be able to use it?

In other words, in 1999 could I have sat down and written a slick web2.0 like website?

It seems like as developers we've gotten much craftier at using javascript. But, how have the other technologies evolved to allow us to build these better mouse traps.

This isn't the answer you're looking for but it's the right one: Anything written today could have been implemented on any turing-complete machine in any point in history, just like any novel written today could have been written in the past 3,000 years. Was the world ready for it or the collective mind gotten to that point? That's a different question.
