sortNumbers.js

/** 

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 []


**/

var array = [];
function solution(array){
    if (array == null){
        return [];
    }
  array.sort(function(a, b){
    return (a-b);
  })
  return array;
}
