ECMA Section: 15.4.2.2 new Array(len)
|
|
|
|
Description: This description only applies of the constructor is
|
|
given two or more arguments.
|
|
|
|
The [[Prototype]] property of the newly constructed
|
|
object is set to the original Array prototype object,
|
|
the one that is the initial value of Array.prototype(0)
|
|
(15.4.3.1).
|
|
|
|
The [[Class]] property of the newly constructed object
|
|
is set to "Array".
|
|
|
|
If the argument len is a number, then the length
|
|
property of the newly constructed object is set to
|
|
ToUint32(len).
|
|
|
|
If the argument len is not a number, then the length
|
|
property of the newly constructed object is set to 1
|
|
and the 0 property of the newly constructed object is
|
|
set to len.
|
|
|
|
This file tests cases where len is a number.
|
|
|
|
The cases in this test need to be updated since the
|
|
ToUint32 description has changed.
