Head JS is a 2.3 kilobyte script that makes it easy to asynchronously load your JavaScript files to prevent blocking. It allows the browser to load the web page separately from the scripts, so the rendering process isn’t held up by the download.
Non-blocking loading is the key to fast pages. Moreover Head JS loads scripts in parallel no matter how many of them and what the browser is. The speed difference can be dramatic especially on the initial page load when the scripts are not yet in cache. It’s your crucial first impression.
If you have a JavaScript-heavy website, it’s worth taking a look at. If you take a look at the demo pages they have set up, the page that uses Head JS to load the scripts definitely displays much faster.
