| 9 ECMA Section: 15.3.5 Properties of Function Instances | |
| 10 new Function(p1, p2, ..., pn, body ) | |
| 11 | |
| 12 Description: | |
| 13 | |
| 14 15.3.5.1 length | |
| 15 | |
| 16 The value of the length property is usually an integer that indicates | |
| 17 the "typical" number of arguments expected by the function. However, | |
| 18 the language permits the function to be invoked with some other number | |
| 19 of arguments. The behavior of a function when invoked on a number of | |
| 20 arguments other than the number specified by its length property depends | |
| 21 on the function. | |
| 22 | |
| 23 15.3.5.2 prototype | |
| 24 The value of the prototype property is used to initialize the internal [[ | |
| 25 Prototype]] property of a newly created object before the Function object | |
| 26 is invoked as a constructor for that newly created object. | |
| 27 | |
| 28 15.3.5.3 arguments | |
| 29 | |
| 30 The value of the arguments property is normally null if there is no | |
| 31 outstanding invocation of the function in progress (that is, the function has been called | |
| 32 but has not yet returned). When a non-internal Function object (15.3.2.1) is invoked, its | |
| 33 arguments property is "dynamically bound" to a newly created object that contains the | |
| 34 arguments on which it was invoked (see 10.1.6 and 10.1.8). Note that the use of this | |
| 35 property is discouraged; it is provided principally for compatibility with existing old code. | |
