Object.keys() fails in Node.js v0.12.7

Object.keys() spits: TypeError: undefined is not a function Version: 0.33.0 Sample test code:

  var keys = {a:1, b:2, c:3}.keys();

This report is invalid.

It’s Object.keys, not Object.prototype.keys.

Try this:

var keys = Object.keys({a:1, b:2, c:3});

Sorry! My mistake. I realize now I read the documentation badly.

So yeah, the correct form is var keys = Object.keys({a:1, b:2, c:3});
