How to serve a JS file to every browser but IE

I dont know why this isn't working. I'm trying to serve a file to good browsers, namely everyone but IE.

<!--[if !IE]>
<script type="text/javascript" src="JS/script.js"></script>
<![endif]开发者_如何学Python-->

but it doesn't get served to any...any idea?

<!--[if !IE]> -->
