            Bug ID: 152320
           Summary: [JSC] TypedArray.prototype.slice() with no argument
                    throws TypeError
    Classification: Unclassified
           Product: WebKit
           Version: Safari 9
          Hardware: Unspecified
                OS: Mac OS X 10.11
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore

Below code throws TypeError saying, "Expected at least one argument".

var arr = new Uint8Array([1,2,3]);
arr.slice();

According to below reference, it seems that TypedArray.prototype.slice() should return [1,2,3] because, when omitted, begin is assumed to be zero and end is assumed to be array.length.
