http://www.mozilla.org/js/tests/library.html for information about these tests, like how to run them and stuff. According to fur, these tests should not get checked out when you check out Mozilla -- you'd have to specifically check out mozilla/js/tests to get all these files. git-svn-id: svn://10.0.0.236/trunk@26348 18797224-902f-48f8-a5cc-f745e15eee43

ECMA Section: 15.4.1.2 Array(len)
|
|
|
|
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 creationi new Array(...) with
|
|
the same arguments.
|
|
|
|
An array is created and returned as if by the
|
|
expression new Array(len).
