```javascript
array.hasPermutation(x, y, [fc], [fm]);
// x:  an array
// y:  permutation?
// fc: map function (v, i, x)
// fm: compare function (a, b)
```

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

var x = [1, 2, 3, 4];
array.hasPermutation(x, [4, 3, 2, 1]);
// true

array.hasPermutation(x, [3, -1, -2, 4]);
// false

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

array.hasPermutation(x, [3, -1, -2, 4], null, v => Math.abs(v));
// true
