File Name: 10.1.6

|
ECMA Section: Activation Object
|
|
Description:
|
|
|
|
If the function object being invoked has an arguments property, let x be
|
|
the value of that property; the activation object is also given an internal
|
|
property [[OldArguments]] whose initial value is x; otherwise, an arguments
|
|
property is created for the function object but the activation object is
|
|
not given an [[OldArguments]] property. Next, arguments object described
|
|
below (the same one stored in the arguments property of the activation
|
|
object) is used as the new value of the arguments property of the function
|
|
object. This new value is installed even if the arguments property already
|
|
exists and has the ReadOnly attribute (as it will for native Function
|
|
objects). (These actions are taken to provide compatibility with a form of
|
|
program syntax that is now discouraged: to access the arguments object for
|
|
function f within the body of f by using the expression f.arguments.
|
|
The recommended way to access the arguments object for function f within
|
|
the body of f is simply to refer to the variable arguments.)
