they’re just references. Basically, in Flash, an array variable is a pointer. A number variable is not. Why? Consider the following

myArray = myOtherArray;  
myNumber = myOtherNumber;

if you change myArray, you are also changing myOtherArray since array variables are references - or pointers - to the array in memory. changing myNumber wont affect myOtherNumber at all since myNumber is a direct copy and not the same position in memory as the original myOtherNumber.

Having pointers gives you direct control over what you use as a copy and what you use as a reference.
