FUNDAMENTALS
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 []
const solution = nums => (nums === null ? [] : nums.sort((a, b) => a - b))
