JavaScript Features

This page is a matrix of JavaScript features. You can use the interface below to compare feature support across browsers. The scripts to test for features are maintained on this wiki: features. The data is kept up to date by you! Even as you read this, your browser is being used to keep this database up to date; thanks for the help!

If you have a very old browser that supports JavaScript but does not support this fancy page, you can still run the tests (although not see the results) by using the micro testing framework. Please do, as having information for old browsers is still interesting!

Editing this wiki requires that you log in. You may log in with OpenID or various popular login providers (Google, Yahoo, etc). All edits to this wiki are logged on a public mailing list, jswiki-commits@lists.codu.org

The sources to all of this are available and released under the MIT/X11 license. The client side is (of course) in JavaScript; you can see it just by viewing the source of this page. The server side is in PHP, the source is available at http://jsfeatures.net/features/source.html .
