- # deep-equal <sup>[![Version Badge][npm-version-svg]][package-url]</sup>
- 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
- ``` 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.
