## power-set-x

Calculates the Power Set of a set S.



### `module.exports(value)` ⇒ Array.<Array> ⏏

This method calculates the Power Set of `value`. Array sparseness is

ignored.

In mathematics, the power set (or powerset) of any set S,

written P(S), ℘(S), P(S), ℙ(S) or 2S, is the set of all subsets of S,

including the empty set and S itself.

**Kind**: Exported function  

**Returns**: Array.<Array> - The power set of `value`.  

**See**: http://en.wikipedia.org/wiki/Power_set

| Param | Type               | Description                                     |

| ----- | ------------------ | ----------------------------------------------- |

| value | Array | The array like `value` to get the power set of. |

**Example**

```js

import powerSet from 'power-set-x';

console.log(powerSet([1, 2, 3])); // [[], [3], [2], [2, 3], [1], [1, 3], [1, 2], [1, 2, 3]]

```
