# deep-equal

## 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`.

## 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
