function calculateMonthlyPayments(transactions) {
  const monthlyPayments = [];

  for (const transaction of transactions) {
    const createdAt = new Date(transaction.createdAt);
    const year = createdAt.getFullYear();
    const month = createdAt.getMonth() + 1; // Months are zero-based

    const existingMonth = monthlyPayments.find(item => item.month === `${year}-${month}`);

    if (existingMonth) {
      existingMonth.totalPayment += transaction.amount;
    } else {
      monthlyPayments.push({
        month: `${year}-${month}`,
        totalPayment: transaction.amount,
      });
    }
  }

  return monthlyPayments;
}

// Example array of transaction objects
const transactions = [
  { createdAt: '2023-08-15T10:00:00.000Z', amount: 100 },
  { createdAt: '2023-08-25T15:30:00.000Z', amount: 150 },
  { createdAt: '2023-09-10T08:45:00.000Z', amount: 200 },
  { createdAt: '2023-09-20T12:00:00.000Z', amount: 300 },
];

const monthlyPayments = calculateMonthlyPayments(transactions);
console.log(monthlyPayments);
