| michael@0 | 8 | File Name: 15.3.5-1.js |
| michael@0 | 9 | ECMA Section: 15.3.5 Properties of Function Instances |
| michael@0 | 10 | new Function(p1, p2, ..., pn, body ) |
| michael@0 | 11 | |
| michael@0 | 12 | Description: |
| michael@0 | 13 | |
| michael@0 | 14 | 15.3.5.1 length |
| michael@0 | 15 | |
| michael@0 | 16 | The value of the length property is usually an integer that indicates |
| michael@0 | 17 | the "typical" number of arguments expected by the function. However, |
| michael@0 | 18 | the language permits the function to be invoked with some other number |
| michael@0 | 19 | of arguments. The behavior of a function when invoked on a number of |
| michael@0 | 20 | arguments other than the number specified by its length property depends |
| michael@0 | 21 | on the function. |
| michael@0 | 22 | |
| michael@0 | 23 | 15.3.5.2 prototype |
| michael@0 | 24 | The value of the prototype property is used to initialize the internal [[ |
| michael@0 | 25 | Prototype]] property of a newly created object before the Function object |
| michael@0 | 26 | is invoked as a constructor for that newly created object. |
| michael@0 | 27 | |
| michael@0 | 28 | 15.3.5.3 arguments |
| michael@0 | 29 | |
| michael@0 | 30 | The value of the arguments property is normally null if there is no |
| michael@0 | 31 | outstanding invocation of the function in progress (that is, the function has been called |
| michael@0 | 32 | but has not yet returned). When a non-internal Function object (15.3.2.1) is invoked, its |
| michael@0 | 33 | arguments property is "dynamically bound" to a newly created object that contains the |
| michael@0 | 34 | arguments on which it was invoked (see 10.1.6 and 10.1.8). Note that the use of this |
| michael@0 | 35 | property is discouraged; it is provided principally for compatibility with existing old code. |
