```javascript
array.sort$(x, [fc], [fm]);
// x:  an array (updated)
// fc: compare function (a, b)
// fm: map function (v, i, x)
// → x
```

```javascript
const array = require("extra-array");

var x = [-2, -3, 1, 4];
array.sort$(x);
// [ -3, -2, 1, 4 ] (compares numbers)

x;
// [ -3, -2, 1, 4 ]

var x = [-2, -3, 1, 4];
array.sort$(x, (a, b) => Math.abs(a) - Math.abs(b));
// [ 1, -2, -3, 4 ]

var x = [-2, -3, 1, 4];
array.sort$(x, null, v => Math.abs(v));
// [ 1, -2, -3, 4 ]
```
