Given an integer representing the number of years a couple has been married, return their most recent anniversary milestone according to this chart:

1"Paper"
5"Wood"
10"Tin"
25"Silver"
40"Ruby"
50"Gold"
60"Diamond"
70"Platinum"
  • If they haven't reached the first milestone, return "Newlyweds".

assert.equal(getMilestone(8), "Wood");

getMilestone(10) should return "Tin".

assert.equal(getMilestone(10), "Tin");

getMilestone(26) should return "Silver".

js
assert.equal(getMilestone(26), "Silver");

getMilestone(45) should return "Ruby".

  const milestones = [

    [25, "Silver"],
    [40, "Ruby"],

      return milestones[i][1];
    }
  }
}
