  // Add two friends:
  await db.friends.bulkAdd([{
    id: 1,
    name: "Foo"
  }, {
    id: 2,
    name: "Bar"
  }]);
  
  // Call bulkGet() to lookup values from given keys in the order of the requested array:
  const [foo, nonExisting, bar] = await db.friends.bulkGet([1, 777, 2]);
  assert (foo.name === "Foo");
  assert (bar.name === "Bar");
  assert (nonExisting === undefined);
}

test().then(()=>{
  console.log("success");
}).catch(error => {
  console.error(error);
});
