According to the ECMA spec, we should throw a RangeError in the
following cases:

  • (length * elementSize) + offset > the size of the array passed in
  • offset % elementSize != 0

In the current implementation, this check was omitted. So, the following
code will cause a crash.

napi_create_typedarray(env, napi_uint16_array, 2 /* length */,
                       buffer, 1 /* byte_offset */, &output_array);

This is a partial cherry-pick from upstream.
