JQuery: Using Conditional Comments To Support Older Version Of Internet Explorer

A lot of you may have wonder why JQuery releases versions 1.x and 2.x, the reason is because the 1.x versions are released to support older versions of Internet Explorer. What a lot of people don't realize is that the 2.x version performs better, so if you have the choice between 1.x and 2.x you should choose the 2.x versions. Use the 1.x versions only if you have to. In this blog we will show how to use conditional comments which Microsoft created in Internet Explorer 5. Since it's specifically created for Internet Explorer other browsers will ignore it. Since Internet Explorer 9 seems to be the divider for support we will use it as the base case for our conditional comments. Here is the code to use the conditional comments to support older versions of Internet Explorer.
