What do you want to use splice() for? Do you have a specific algorithm for sorting in your mind?

You could use the following, trivial (and slow) algorithm that uses splice() to remove single elements from your array.

• create a new, empty array which will contain the sorted numbers
• while the unsorted-array contains members
  • loop through the unsorted array to find the smallest element
  • cut the smallest element from the list, using splice
  • push that element at the end of your sorted array

HTH, Rata (who hopes that you will not use the algorithm above when writing "real" code ;-)
