How can I query data without having to map the values with JavaScript?

async function getMovieWithActors(title: string) {
  return db
    .select({
      id: schema.movie.id,
      title: schema.movie.title,
      released: schema.movie.released,
      actor: { id: schema.actor.id, actor: schema.actor.name },
    })
    .from(schema.movie)
    .innerJoin(schema.movieActor, eq(schema.movie.id, schema.movieActor.movieId))
    .innerJoin(schema.actor, eq(schema.actor.id, schema.movieActor.actorId))
    .where(eq(schema.movie.title, title))
}

// output
[
  {
    id: 1,
    title: "The Shawshank Redemption",
    released: "1994",
    actor: {
      id: 1,
      actor: "Tim Robbins",
    },
  }, {
    id: 1,
    title: "The Shawshank Redemption",
    released: "1994",
    actor: {
      id: 6,
      actor: "Morgan Freeman",
    },
  }
]
