Has anyone ever found a good use for ES2015 object super? eg. ({ foobar() { super.foobar(); }, __proto__: obj, }) I've never seen it used once and feels like an unnecessary addition to the language.

it was/could be more useful when there was a way to change/set the HomeObject of a method. It does seem pretty weird tho, still.

Any idea who I could bug to find the rationale, or meeting notes? I’m curious to see the history since I trust there’s a good reason.

i was around for removing the “set home object” mechanism pre es6, but not for the rationale - @awbjs can probably speak to it best.

The rationale for removing “set home object”? There was concern it would be a foot gun. It’s use case was to allow user land creation of class-like abstraction mechanisms that supported `super` but didn’t require use of syntactic `class` declarations.

the rationale for super in objects at all, i think was the question

Super is a classic OO language feature that enables a subclass to enhance an inherited method typically by adding before/after behavior. EG: class sub extends base { m() { // before super.m(); // after } }
