Discussion on: LeetCode 1169. Invalid Transactions (javascript solution)

[CJLeverett]

I don't get it, I did something almost exactly the same but not sure why it won't pass.

function invalidTransactions(transactions) {
  const review = {};
  const invalidTransactions = [];

  for (const t of transactions) {
    const [name, time, , city] = t.split(',');

    if (name in review) review[name].push({ time, city });
    else review[name] = [{ time, city }];
  }

  for (const transaction of transactions) {
    const [name, time, amount, city] = transaction.split(',');
    const prevTransactions = review[name];

    if (amount > 1000) {
      invalidTransactions.push(transaction);
    }

    for (const prevTransaction of prevTransactions) {
      const { time: prevTime, city: prevCity } = prevTransaction;

      if (city !== prevCity && Math.abs(time - prevTime) <= 60) {
        invalidTransactions.push(transaction);
      }
    }
  }

  return Array.from(invalidTransactions);
}
