How long ago could Jquery have been written?
<p>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?</p>

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

<p>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.</p>
