Browser Support
E4X is supported by Mozilla's Rhino, used in OpenOffice.org and several other projects, and SpiderMonkey, used in Firefox, Thunderbird, and other XUL-based applications. It is also supported by Tamarin, the JavaScript engine used in the Flash virtual machine. It is not supported by Nitro (Safari), V8 (Google Chrome), Carakan (Opera), nor Internet Explorer.
As of Firefox 10, E4X syntax is no longer accepted in SpiderMonkey when ECMAStrict 5 "strict mode" is enabled. According to Brendan Eich, "This thus signals start of deprecation for E4X in SpiderMonkey." and as of Firefox 17, E4X will likely be disabled by default

Famous quotes containing the word support:
“The wisest thing a parent can do is to let preschool children figure out themselves how to draw the human figure, or solve a whole range of problems, from overcoming Saturday-morning boredom to dealing with a neighborhood bully. But even while standing on the sidelines, parents can frequently offer support in helping children discover what they want to accomplish.”
—John F. Clabby (20th century)
