The object is extensible, so need to define what happens for new properties. The existing properties are not writable but they are configurable, so need to define what happens if they're made writable and then set. 91610 1 cam 2013-08-04 08:35:29 +0000 I defined [[DefineOwnProperty]] in bug 21929, and [[Delete]] here: http://dev.w3.org/cvsweb/2006/webapi/WebIDL/Overview.xml.diff?r1=1.685;r2=1.686;f=h http://dev.w3.org/cvsweb/2006/webapi/WebIDL/v1.xml.diff?r1=1.127;r2=1.128;f=h 91843 2 bzbarsky 2013-08-09 19:30:15 +0000 Er, I get bug 21929 comment 2 actually belongs here... 99201 3 cam 2014-01-27 21:40:57 +0000 (In reply to Boris Zbarsky from bug 21929 comment #2) > The [[Delete]] defined in the spec now works for ES5 but not ES6: in ES6 > [[Delete]] just returns a boolean indicating success or not and the caller > throws or not based on strict mode... OK, fixed: https://github.com/heycam/webidl/commit/a4e5e47940bd7fb1e0ea9408a4d45a508c543af4
