### maxN
|
|
|
|
Returns the `n` maximum elements from the provided array. If `n` is greater than or equal to the provided array's length, then return the original array(sorted in descending order).
|
|
|
|
Use `Array.sort()` combined with the spread operator (`...`) to create a shallow clone of the array and sort it in descending order.
|
|
Use `Array.slice()` to get the specified number of elements.
|
|
Omit the second argument, `n`, to get a one-element array.
|
|
|
|
```js
|
|
const maxN = (arr, n = 1) => [...arr].sort((a, b) => b - a).slice(0, n);
|
|
```
|
|
|
|
```js
|
|
maxN([1, 2, 3]); // [3]
|
|
maxN([1, 2, 3], 2); // [3,2]
|
|
maxN([1, 2, 3], 4); // [3,2,1]
|
|
```
