#object-is 
ES6-compliant shim for Object.is - differentiates between -0 and +0, and can compare to NaN.
Essentially, Object.is returns the same value as === - but true for NaN, and false for -0 and +0.
Example
Object.is = require('object-is');
var assert = require('assert');
assert.ok(Object.is());
assert.ok(Object.is(undefined));
assert.ok(Object.is(undefined, undefined));
assert.ok(Object.is(null, null));
assert.ok(Object.is(true, true));
assert.ok(Object.is(false, false));
assert.ok(Object.is('foo', 'foo'));
var arr = [1, 2];
assert.ok(Object.is(arr, arr));
assert.notOk(Object.is(arr, [1, 2]));
assert.ok(Object.is(0, 0));
assert.ok(Object.is(-0, -0));
assert.notOk(Object.is(0, -0));
assert.ok(Object.is(NaN, NaN));
assert.ok(Object.is(Infinity, Infinity));
assert.ok(Object.is(-Infinity, -Infinity));
