How do I include a javascript if it’s IE, and another javascript if everything else?

I want to include <script src="ie.js"> if the browser is IE.

Otherwise, include all.js for all other browsers.

How can I do this?

Answer

You can do this using conditional comments. Example:

<!--[if IE]>
    <script src="ie.js">
<![endif]-->
<!--[if !IE]><!-->
    <script src="all.js"></script>
<!--<![endif]-->
