njs_buffer.c:

static njs_int_t
njs_buffer_byte_length(njs_vm_t *vm, njs_value_t *args, njs_uint_t nargs,
njs_index_t unused, njs_value_t *retval)
{
size_t size;
njs_value_t *value;
const njs_buffer_encoding_t *encoding;

value = njs_arg(args, nargs, 1);

switch (value->type) {
case NJS_TYPED_ARRAY:
    njs_set_number(retval, njs_typed_array(value)->byte_length);
    return NJS_OK;

Should we set retval=0 here in case of detached buffer?

Need we add similar checks for detached array after some other njs_typed_array() invocations?

Otherwise looks good.
