932375 - Implement ES6 Object.assign and Object.mixin

Status: RESOLVED DUPLICATE of bug 937855

(Core :: JavaScript Engine, defect)

Description

[Brandon Benvie [:benvie]]

ES6 draft spec (October 2013 revision):

* Object.assign (target, source) - 19.1.2.1
  Copies the values of all of the enumerable own properties from a source to a target. Uses [[Get]] on the source and [[Put]] on the target, so will invoke getters/setters.

* Object.mixin (target, source) - 19.1.2.15
  Copies the definitions of all of the own properties from a source to a target. Supports rebinding of `super` which we can ignore until we support classes.

I think this bug should be splited to implementaion of Object.assign and implementation of Object.mixin .
Because implementing Object.assign is easy but Object.mixin is difficult and it depending on something related to "super" mechanism

Comment 2

Object.mixin has been dropped from ES6

Given comment 2, this is a straight dupe of bug 937855.
