title: Javascript optimizations for Internet Explorer
body: <p>It is well known that the Internet Explorer Javascript Engines are way behind in terms of performance, in particular IE 8 and older, when compared to Chrome, Safari (Webkit) or Firefox (Mozilla).</p>
  
  <p>When developing a web application with significant javascript functionality, IE performs much worst than the others.</p>
  
  <p>Are there any practices that could help improve your javascript code so the divide between the  good performers (non-IE) and the bad performer (IE) is not that wide?</p>
