trying to set string array back to a text area

Question

0.00/5 (No votes)

See more:

The code creates an array then sets it to a text-area.
I then return it turn split it back to an array sort it and attempt to replace the commas with new lines and return it to another text-area.
However I can't replace the commas or set the second text-area with the values.
Does anyone have any ideas? I really appreciate it.

The first thing that stands out is that sort() sorts the members of the original array so you don't need to assign the result to another array.

Converting an array to a string performs a join with a comma as the separator - the easiest way to use a "\n" instead of a comma is to explicitly use theArray.join('\n').
