+  22.2.4.5 TypedArray ( buffer [ , byteOffset [ , length ] ] )
+
+  This description applies only if the TypedArray function is called with at
+  least one argument and the Type of the first argument is Object and that
+  object has an [[ArrayBufferData]] internal slot.

+  ...
+  14. Else,
+    a. Let newLength be ? ToLength(length).
+    b. Let newByteLength be newLength × elementSize.
+    c. If offset+newByteLength > bufferByteLength, throw a RangeError exception.
