Examples

Example 1

watchers2 = addElement(watchers, currentUser());

The result returned by the function is assigned to a new array watchers2, so the initial array watchers will not be modified.

Example 2

watchers = addElement(watchers, currentUser());

The result returned by the function is assigned to the same array watchers, so the initial array watchers will be modified.

If elem is not the same type as declared in the array definition, the function returns error.

Starting with version 2.5 is easier for you to just use the '+' operator to add elements to an array. array = array + element it is a simple and more meaningful way to express it. array += element is even better.
