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:
“Never support two weaknesses at the same time. It’s your combination sinners—your lecherous liars and your miserly drunkards—who dishonor the vices and bring them into bad repute.”
—Thornton Wilder (1897–1975)
