Asynchronous Javascript is for Web the best thing since sliced bread

This post was triggered by a recently announced asynchronous Google analytics tracking code, and then I thought to my self - it was about time it was brought to mainstream.

When something loads asynchronously on a web page, that means it does not block other content from loading and your browser can load other things.

This is especially important on today's sites where amount of Javascript code is becoming excessive. In other words, asynchronous loading = faster page loads = happier visitors (= more revenue).

Implementing new Google analytics asynchronous tracking code is as easy as removing the old one and placing the new one, and now you are safe to put it in the header as well. And because it will load now a bit sooner than the old one, it might catch few more visits that your old code missed as the visitors quit the page before it was fully loaded.

My baby startup Cleveritics will also use a full asynchronous tracking code.
