Check out "Table 35" in the latest ES6 draft. For example it provides the
following for Uint8Array:

Constructor Name: Uint8Array
Element Type: Uint8
Element Size: 1
Conversion Operation: ToUint8
Description: 8-bit unsigned integer
Equivalent C Type: unsigned char

So, with ES6 we now have: ToInt8, ToUint8, ToUint8Clamp, ToInt16, ToUint16,
ToInt32 and ToUint32
