## 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]
|
|
```
