deep-is

Node's assert.deepEqual() algorithm as a standalone module. Exactly like deep-equal except for the fact that deepEqual(NaN, NaN) === true.
This module is around 5 times faster than wrapping assert.deepEqual() in a try/catch.

var equal = require('deep-is');
console.dir([
    equal(
        { a : [ 2, 3 ], b : [ 4 ] },
        { a : [ 2, 3 ], b : [ 4 ] }
    ),
    equal(
        { x : 5, y : [6] },
        { x : 5, y : 6 }
    )
]);

var deepIs = require('deep-is')

deepIs(a, b)

Compare objects a and b, returning whether they are equal according to a recursive equality algorithm.With npm do:

npm install deep-is

With npm do:

npm test
