Javascript (ES6) const with curly braces

I'm new to ECMAScript 6, and while trying to learn Ember, I've seen the following code style occassionally:

const {
  abc,
  def
} = Object;

I've searched Google and many sites explaining the new ES6 specifications. I know this is not the current implementation, because my console gives an error when I input that.

What does this code mean?

UPDATE

I pasted this snippet into Babel's transpiler, and this is what it returned:

"use strict";

var abc = Object.abc;
var def = Object.def;

I'm still confused as to what this is trying to accomplish.
