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