#20 - Sort Numbers CodeWars Kata (7 kyu)


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 []

My solution:

function solution(nums){
  return nums !== null ? nums.sort((a,b)=> a-b) : [] 
Enter fullscreen mode Exit fullscreen mode


I returned a value using a conditional, if the nums array isn't null it will sort the nums array using a comparison function, it will rest a-b so it returns the nums array sorted correctly and if the element is null it will return an empty array
