# N max elements

JavaScript, Math · Oct 21, 2020

Returns the `n` maximum elements from the provided array.

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