Benchmark: min check - MeasureThat.net

Script Preparation code:

// 假的 entityById 資料
const entityById = {};
for (let i = 1; i <= 200; i++) {
  const price = (i * 10).toString(); // 產生 10, 20, 30, ..., 1000 的 price key
  const amount = Math.floor(Math.random() * 100) + 1; // 隨機產生 1 到 100 的 amount
  entityById[price] = amount;
}

// 假的 data 資料
const data = [];
for (let i = 0; i < 20; i++) {
  const price = ((Math.floor(Math.random() * 100) + 1) * 10).toString(); // 隨機選擇 10, 20, 30, ..., 1000 的 price key
  const amount = Math.floor(Math.random() * 101); // 隨機產生 0 到 100 的 amount
  data.push([price, amount]);
}
