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

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

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

array.isSuffix(x, [-3, -4]);
// false

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

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