ECMAScript 5 and ES5 are also used, I just picked one that worked here.

[michaelficarra]

Aaahh let's change those.

#1832

Couple others from my list

• var a = _(), b = a.chain() doesn't create 2 instances of _
• _.omit can handle non string arguments
• _.partition is now called with index and object
• _.matches creates a shallow clone of your object
• union and difference exclude non arrays Restrict _.union and _.difference to accept arrays only #1428

[jdalton]

• _.flatten no longer works on objects
  (it was an undocumented side affect of previously using _.each in its implementation)
• _.matches now iterates over own properties of the source object

var a = _(), b = a.chain() doesn't create 2 instances of _

Is this public-facing though? Would this be breaking for anything?

_.flatten no longer works on objects

This should be fine since _.flatten is an arrays method and it wouldn't be expected to work with objects.

union and difference exclude non arrays

underscore/index.html

Lines 2078 to 2079 in 5b0152c

	For consistency, <tt>_.union</tt> and <tt>_.difference</tt> now
	only work with arrays and not variadic args.

I'll grab the rest.

Cool, wanna do the honors?

It was reported here so figured I'd pass it along.
