arrayDeleteElement
Description
If elem is an element of the array type, returns a new array without the specified element.
Parameters
Return Type
Array
Example
watchers = deleteElement(watchers, currentUser());
The result returned by the function is assigned to the the same array watchers, so the initial array watchers will be modified.
If array is not defined as an array, the function returns error.
If elem is not the same type as declared in the array definition, the function returns error.
Starting with version 2.5, there is a more powerful way to express these operations: array = array - element; or even better array -= element;
