New issue 2376 by [email protected]: "delete obj[0]"("obj[0]" is
non-configurable property) should return "false"
http://code.google.com/p/v8/issues/detail?id=2376
via http://uupaa.hatenablog.com/entry/2012/10/19/015437
test code:
(function () {
var obj = {};
Object.defineProperty(obj, 0, {configurable: false, value: 0});
return (delete obj[0]);
}());
test page: http://jsfiddle.net/syoichi/Ja4UL/
On Windows 7 Home Premium SP1 64bit,
Mozilla Firefox Nightly 19.0a1(buildID 20121020030554)[SpiderMonkey],
Apple WebKit r131444[JavaScriptCore],
Opera Next 12.10 beta x64(build 1627)[Carakan] return "false",
but Chromium 24.0.1304.0(163201)[V8 3.14.4.1] return "true".
"delete obj[0]" should return "false", because "obj[0]" is non-configurable
property.
