| 8 File Name: 15.4.1.1.js | |
| 9 ECMA Section: 15.4.1 Array( item0, item1,... ) | |
| 10 | |
| 11 Description: When Array is called as a function rather than as a | |
| 12 constructor, it creates and initializes a new array | |
| 13 object. Thus, the function call Array(...) is | |
| 14 equivalent to the object creation new Array(...) with | |
| 15 the same arguments. | |
| 16 | |
| 17 An array is created and returned as if by the expression | |
| 18 new Array( item0, item1, ... ). | |
