#28549 — function in hash

Hi there,

I wrote some code below (Format A) by mistake:

Format A:
------------------
var a = {
  x: 1,
  y: 2,
  foo() {
    alert("foo");
  },
};

Actually I intend to write (Format B):

Format B:
------------------
var a = {
  x: 1,
  y: 2,
  foo: function() {
    alert("foo");
  },
};

However, to my surprise, Format A works well in Firefox 38.2.0, I haven't tried other browser, am I missing anything? I thought Format A's syntax is wrong.

Thanks,
Stone

Another ES5 black magic?

Nope, ES6 magic. It's called a method definition:
