### Array dropRight
Returns a new array with `n` elements removed from the right
Checks if `n` is shorter than the given array and slices it accordingly or returns an empty array
```js
const (arr, n = 1) => n < arr.length ? arr.slice(0, arr.length - n) : []
//dropRight([1,2,3]) -> [1,2]
//dropRight([1,2,3], 2) -> [1]
//dropRight([1,2,3], 42) -> []
```
