The HTML5 test - How well does your browser support HTML5?
The HTML5 test score is an indication of how well your browser supports the upcoming HTML5 standard and related specifications. Even though the specification isn't finalized yet, all major browser manufacturers are making sure their browser is ready for the future. Find out which parts of HTML5 are already supported by your browser today and compare the results with other browsers. The HTML5 test does not try to test all of the new features offered by HTML5, nor does it try to test the functionality of each feature it does detect. Despite these shortcomings we hope that by quantifying the level of support users and web developers will get an idea of how hard the browser manufacturers work on improving their browsers and the web as a development platform.

Asynchronous script execution The async attribute for the script element enables the associated script to load and execute asynchronously with respect to the rest of the page. That is, the script will load and execute in the background while the page continues to be parsed. For pages using processing-intensive scripts, the async attribute can significantly increase page-load performance. The async attribute is part of the World Wide Web Consortium (W3C) HTML5 standard and is designed for situations where dependencies on a script do not exist, but the script still needs to run as soon as possible. Without the async (or defer ) attribute, a script can block other page content from loading.
