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_t description has changed.
