Actionscript 3 – arguments of each function
An arguments object is used to store and access a function’s arguments. Within a function’s body, you can access its arguments object by using the local arguments variable. The arguments are stored as array elements: the first is accessed as arguments[0], the second as arguments[1], and so on. The arguments.length property indicates the number of arguments passed to the function. There may be a different number of arguments passed than the function declares.
