## Stable

A stable array sort, because `Array#sort()` is not guaranteed stable.

#### From npm

Install with:

```sh
npm install stable
```

Then use it in Node.js or some other CommonJS environment as:

```js
const stable = require('stable')
```

#### From the browser

Include [`stable.js`] or the minified version [`stable.min.js`]
in your page, then call `stable()`.

 [`stable.js`]: https://raw.github.com/Two-Screen/stable/master/stable.js
 [`stable.min.js`]: https://raw.github.com/Two-Screen/stable/master/stable.min.js

#### Usage

The default sort is, as with `Array#sort`, lexicographical:

```js
stable(['foo', 'bar', 'baz'])  // => ['bar', 'baz', 'foo']
stable([10, 1, 5])             // => [1, 10, 5]
```

Unlike `Array#sort`, the default sort is **NOT** in-place. To do an in-place
sort, use `stable.inplace`, which otherwise works the same:

```js
const arr = [10, 1, 5]
stable(arr) === arr          // => false
stable.inplace(arr) === arr  // => true
```

A comparator function can be specified:

```js
// Regular sort() compatible comparator, that returns a number.
// This demonstrates the default behavior.
const lexCmp = (a, b) => String(a).localeCompare(b)
stable(['foo', 'bar', 'baz'], lexCmp)  // => ['bar', 'baz', 'foo']

// Boolean comparator. Sorts `b` before `a` if true.
// This demonstrates a simple way to sort numerically.
const greaterThan = (a, b) => a > b
stable([10, 1, 5], greaterThan)  // => [1, 5, 10]
```
