    const fetches = Array.from({length: increment}).map(() => vote({ id, direction }))
  
    const results = await Promise.all(fetches);
    const resultJsons = await Promise.all(results.map(res => res.json()))

    currentScore = Math.max(...resultJsons.map(v => v.new_score));

   if (
      (direction == "up" && currentScore >= target) ||
      (direction == "down" && currentScore <= target)
    ) {
      console.log("The deed has been done");
