### maxN
Returns the `n` maximum elements from the provided array. If `n` is greater than or equal to the provided array's length than return the original array(sorted in descending order).
Sort's the array's shallow copy in descending order and returns the first n elements
Skip the second argument to get a single element(in the form of a array)
``` js
const maxN = (arr,n = 1) => {
let rra = [...arr].sort((a,b) => b-a)
return rra.splice(0,n)
}
```
``` js
maxN([1,2,3]); // [3]
maxN([1,2,3],2); // [3,2]
maxN([1,2,3],4); // [3,2,1]
```
