```javascript
array.searchRight(x, ft);
// x:  an array
// ft: test function (v, i, x)
// → index of value, -1 if not found
```

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

var x = [1, 2, 3, 2, 5];
array.searchRight(x, 2);
// 3              ^

var x = [1, 2, 3, -2, 5];
array.searchRight(x, 2, (a, b) => Math.abs(a) - Math.abs(b));
// 3               ^

array.searchRight(x, 2, null, v => Math.abs(v));
