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.
