如何根据在react native中创建事务的日期对事务列表进行分组？

function groupTransactionsByDate(transactions) {
  return transactions.reduce((groups, transaction) => {
    const date = transaction.date; // 假设事务对象的日期属性为date

    if (!groups[date]) {
      groups[date] = [];
    }

    groups[date].push(transaction);
    return groups;
  }, {});
}

const transactions = [
  { id: 1, title: 'Transaction 1', date: '2022-01-01' },
  { id: 2, title: 'Transaction 2', date: '2022-01-01' },
  { id: 3, title: 'Transaction 3', date: '2022-01-02' },
  // 其他事务对象...
];

const groupedTransactions = groupTransactionsByDate(transactions);
console.log(groupedTransactions);

{
  '2022-01-01': [
    { id: 1, title: 'Transaction 1', date: '2022-01-01' },
    { id: 2, title: 'Transaction 2', date: '2022-01-01' }
  ],
  '2022-01-02': [
    { id: 3, title: 'Transaction 3', date: '2022-01-02' }
  ]
}
