  look at jQuery... if you have never read the source for it, as a developer, you are doing yourself an injustice. not only has john resig worked on it, but also yehuda katz, so there are some really smart people who coded it to learn from.

    In my opinion, having read parts of jQuery's source code on various occasions… You should only read it for entertainment value, it makes for fascinating brain teasers. Here's one snippet I had the opportunity to read recently: contains = hasCompare || rnative.test( docElem.contains ) ? function( a, b ) { var adown = a.nodeType === 9 ? a.documentElement : a, bup = b && b.parentNode; return a === bup || !!( bup && bup.nodeType === 1 && ( adown.contains ? adown.contains( bup ) : a.compareDocumentPosition && a.compareDocumentPosition( bup ) & 16 )); } : function( a, b ) { if ( b ) { while ( (b = b.parentNode) ) { if ( b === a ) { return true; } } } return false; };

      i have no doubts. i haven't read through the source in years, but i'm sure there are tons of wtfs in there. those dudes had to do some pretty effed up stuff in order to make it work, and keep working, with the slew of browsers and incompatibilities back then.
