Iterates over the dynamic properties of an object or elements in an array and executes statement for each property or element.Object properties are not kept in any particular order, so properties may appear in a seemingly random order.Fixed properties, such as variables and methods defined in a class, are not enumerated by the for..in statement. To get a list of fixed properties, use the describeType() function, which is in the flash.utils package.
