ECMA Section: 15.3.5 Properties of Function Instances
|
|
new Function(p1, p2, ..., pn, body )
|
|
|
|
Description:
|
|
|
|
15.3.5.1 length
|
|
|
|
The value of the length property is usually an integer that indicates
|
|
the "typical" number of arguments expected by the function. However,
|
|
the language permits the function to be invoked with some other number
|
|
of arguments. The behavior of a function when invoked on a number of
|
|
arguments other than the number specified by its length property depends
|
|
on the function.
|
|
|
|
15.3.5.2 prototype
|
|
The value of the prototype property is used to initialize the internal [[
|
|
Prototype]] property of a newly created object before the Function object
|
|
is invoked as a constructor for that newly created object.
|
|
|
|
15.3.5.3 arguments
|
|
|
|
The value of the arguments property is normally null if there is no
|
|
outstanding invocation of the function in progress (that is, the function has been called
|
|
but has not yet returned). When a non-internal Function object (15.3.2.1) is invoked, its
|
|
arguments property is "dynamically bound" to a newly created object that contains the
|
|
arguments on which it was invoked (see 10.1.6 and 10.1.8). Note that the use of this
|
|
property is discouraged; it is provided principally for compatibility with existing old code.
