DESCRIPTION:

Finish the solution so that it sorts the passed in array of numbers. If the function passes in an empty array or null/nil value then it should return an empty array.

 

For example:

solution([1, 2, 10, 50, 5]); // should return [1,2,5,10,50]
solution(null); // should return []

 

코드

function solution(nums){
  return (nums || []).sort((a, b) => a - b);
}
