const db = new Database()

  id: "1",
  name: "John",
  age: 30,
  job: "Engineer",
  certifications: ["AWS", "Azure", "GCP"]
})

db.append({
  id: "2",
  name: "Jane",
  age: 30,
  job: "Engineer",
  certifications: ["AWS", "Azure", "Docker"]
})

/**
 * Find people whose job is `Engineer` and who have the `GCP` certification, order by ascending age, then order by descending id if they have the same age
 */
const [john] = db.get({ age: "ascending", id: "descending" }, { job: "Engineer", certifications: ["GCP"] })

• Any column that can be converted to number will be orderable (e.g. 0.1, "0.1", 1n, "0x1")
• Arrays are filtered with inter / inner join / "and" (e.g. ["GCP", "AWS"] -> arrays containing both Azure and GCP)
