Underscore.js flatten object keys to array

Supposing I have such object:

var obj = {
  'a': 'fizzle',
  'b': 'wizzle',
  'c': 'bum',
  'd': 'crum'
}

I would like to take the key names and flatten these into an array, like so:

// -> ['a', 'b', 'c', 'd'];

I could achieve this with a simple object loop, however I am wondering if there is a common underscore utility that could turn it into a one-liner. I looked through the underscore functions and couldn't find one for this.

You could just use Object.keys() method available on the native Object constructor , Which outputs the original objects own enumerable properties. 

Object.keys(obj);
