deep-equal

Node's assert.deepEqual() algorithm as a standalone module, that also works in browser environments.

It mirrors the robustness of node's own assert.deepEqual and is robust against later builtin modification.

example

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

methods

var deepEqual = require('deep-equal')

deepEqual(a, b, opts)

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

If opts.strict is true, use strict equality (===) to compare leaf nodes. The default is to use coercive equality (==) because that's how assert.deepEqual() works by default.

install

With npm do:

npm install deep-equal

test

With npm do:
