ECMA Section: Arguments Object
|
|
Description:
|
|
|
|
When control enters an execution context for declared function code,
|
|
anonymous code, or implementation-supplied code, an arguments object is
|
|
created and initialized as follows:
|
|
|
|
The [[Prototype]] of the arguments object is to the original Object
|
|
prototype object, the one that is the initial value of Object.prototype
|
|
(section 15.2.3.1).
|
|
|
|
A property is created with name callee and property attributes {DontEnum}.
|
|
The initial value of this property is the function object being executed.
|
|
This allows anonymous functions to be recursive.
|
|
|
|
A property is created with name length and property attributes {DontEnum}.
|
|
The initial value of this property is the number of actual parameter values
|
|
supplied by the caller.
|
|
|
|
For each non-negative integer, iarg, less than the value of the length
|
|
property, a property is created with name ToString(iarg) and property
|
|
attributes { DontEnum }. The initial value of this property is the value
|
|
of the corresponding actual parameter supplied by the caller. The first
|
|
actual parameter value corresponds to iarg = 0, the second to iarg = 1 and
|
|
so on. In the case when iarg is less than the number of formal parameters
|
|
for the function object, this property shares its value with the
|
|
corresponding property of the activation object. This means that changing
|
|
this property changes the corresponding property of the activation object
|
|
and vice versa. The value sharing mechanism depends on the implementation.
