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.
