+# deep-equal
+
+Node's `assert.deepEqual() algorithm` as a standalone module.
+
+This module is around [5 times faster](https://gist.github.com/2790507)
+than wrapping `assert.deepEqual()` in a `try/catch`.
+
+[![browser support](https://ci.testling.com/substack/node-deep-equal.png)](https://ci.testling.com/substack/node-deep-equal)
+
+[![build status](https://secure.travis-ci.org/substack/node-deep-equal.png)](https://travis-ci.org/substack/node-deep-equal)
+
+# example
+
+``` js
+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
+
+``` js
+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](http://npmjs.org) do:
+
+```
+npm install deep-equal
+```
+
+# test
+
+With [npm](http://npmjs.org) do:
+
+```
+npm test
+```
+
+# license
+
+MIT. Derived largely from node's assert module.
