The title of the thread is "object static methods rationale doc" and the first post has a link to the doc. The first mention of I see of "extend" was by Brendan, who merely asked: "Did you consider prototype's Object.extend method." To which Doug replied: "Yes we did." And Allen later replied: "As far as I can recall, we didn't discuss a specific formulation that corresponds to Object.extend" > Mozilla has offered a proposal and is looking to implement it in SpiderMonkey. I see a bug report for that mentioned in the thread. "Object.extend" seems to be a misnomer for augmenting objects. It might contrast with Prototype.js Object.extend. "augment" or "mixin" or even "flatten" would do the trick. /** * Object.create * @description Creates a new object based on \ * subject with propertyDescriptor as the [[Prototype]] * @param subject * @param {PropertyDescriptor} propertyDescriptor * properties with attributes for A's prototype */ 1) Object.create doesn't modify subject/receiver, extend does 2) Object.create takes objects, extend takes 2 functions + 1 object descriptor > > The aforementioned Object.create and YAHOO.lang.extend are a completely > separate utilities which should be judged on their own merits. And as I type this, I see now a new message from Allen: "I thought that we were generally discussing how Object.extent related to the Object meta functions that are already in the 3.1 draft." That is what I though, too. Garrett > > --John > _______________________________________________ Es4-discuss mailing list Es4-discuss@mozilla.org https://mail.mozilla.org/listinfo/es4-discuss
