# sort-keys [![Build Status](https://travis-ci.org/sindresorhus/sort-keys.svg?branch=master)](https://travis-ci.org/sindresorhus/sort-keys)

> Sort the keys of an object

Useful to get a deterministically ordered object, as the order of keys can vary between engines.


## Install

```
$ npm install --save sort-keys
```


## Usage

```js
const sortKeys = require('sort-keys');

sortKeys({c: 0, a: 0, b: 0});
//=> {a: 0, b: 0, c: 0}

sortKeys({b: {b: 0, a: 0}, a: 0}, {deep: true});
//=> {a: 0, b: {a: 0, b: 0}}

sortKeys({c: 0, a: 0, b: 0}, {
	compare: (a, b) => -a.localeCompare(b)
});
//=> {c: 0, b: 0, a: 0}
```
