New issue 2747 by [email protected]: Implement ArrayBuffer.isView()
http://code.google.com/p/v8/issues/detail?id=2747

The typed array spec editor's draft at http://www.khronos.org/registry/typedarray/specs/latest/ and the current ES6 working draft of May 14, 2013 contain a new static function, ArrayBuffer.isView(arg), which returns 'true' if the argument is a typed array view (either one of the array-like types or DataView). This needs to be implemented once typed arrays are implemented completely in V8 rather than partly split between V8 and Blink as is the case currently.

Note that there is a bug in the spec of ArrayBuffer.isView in the ES6 draft of May 14, 2013. It should not return true for exotic Array objects. https://bugs.ecmascript.org/show_bug.cgi?id=1570 has been filed about this issue.
