Task Purpose
The toString (array) task is used to return a string representing the contents of a given array. The string representation contains each array element separated by a comma. The task returns null if the array is empty.
Potential Use Case
This task returns a string with all the array values, separated by commas. If a recent query into a ticketing database has populated an array with open ticket numbers, you could use this method to convert the array and send an email that contains a comma separated list of those ticket numbers.

Example

The return variable shows each element in the array separated by a comma. In this example, no white space is used since we did not set a spacer variable.
