### dropRight
|
||||||
|
|
||||||
|
Returns a new array with `n` elements removed from the right
|
||||||
|
|
||||||
|
Check if `n` is shorter than the given array and use `Array.slice()` to slice it accordingly or return an empty array.
|
||||||
|
|
||||||
|
```js
|
||||||
|
const dropRight = (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) -> []
|
||||||
|
```
