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

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

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

array.hasInfix(x, [-2, -3]);
// false

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

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