# 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.
