N min elements	snippet	math	digital-nomad-8	2020-10-21T21:54:53+03:00

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]
