| File Name: 15.4.1.1.js |
| ECMA Section: 15.4.1 Array( item0, item1,... ) |
| |
| Description: When Array is called as a function rather than as a |
| constructor, it creates and initializes a new array |
| object. Thus, the function call Array(...) is |
| equivalent to the object creation new Array(...) with |
| the same arguments. |
| |
| An array is created and returned as if by the expression |
| new Array( item0, item1, ... ). |
