Description
The Arguments object is defined only within a function body, and
within every function body, the local variable
arguments
refers to the Arguments object for that
function. The Arguments object is an array whose elements are the
values that were passed as arguments to the function. Element 0 is
the first argument, element 1 is the second argument, and so on. All
values passed as arguments become array elements of the Arguments
object, whether or not those arguments are given names in the
function declaration.
