Drill 15: Why this way — Dates and numbers

const now = new Date();
console.log(now.getFullYear());

const start = new Date("2024-01-01");
const end = new Date("2024-01-08");
const diffMs = end - start;
const diffDays = diffMs / (1000 * 60 * 60 * 24);
console.log(diffDays);

const money = new Intl.NumberFormat("en-US", {
  style: "currency",
  currency: "USD"
});
console.log(money.format(1234.5));

console.log(0.1 + 0.2);
const price = (0.1 + 0.2).toFixed(2);
console.log(price);
