# N min elements

JavaScript, Math · Oct 21, 2020

Returns the `n`

minimum 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 ascending 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 ascending order).

`const minN = (arr, n = 1) => [...arr].sort((a, b) => a - b).slice(0, n);`

```
minN([1, 2, 3]); // [1]
minN([1, 2, 3], 2); // [1, 2]
```
