```javascript
array.reduceRight(x, fr, [acc]);
// x:   an array
// fr:  reduce function (acc, v, i, x)
// acc: initial value
```

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

var x = [1, 2, 3, 4];
array.reduceRight(x, (acc, v) => acc+v);
// 10

array.reduceRight(x, (acc, v) => acc+v, 100);
// 110
```
