Как посчитать сумму за день?

Подскажите, как посчитать общую сумму за каждый день
var dailyBalance = 0.00;
$.ajax({
    url: '../list.php',
    type: "GET",
    dataType: "json",
    success: function(json) {
        if (typeof(json.response) == 'object') {
            const _account = json.response.items.reduce((acc, cur, i, a) => {
                const index = acc.findIndex(item => item.date === cur.date)
                if (index !== -1) {

                    if (cur.type == 1) {
                        dailyBalance = dailyBalance + Number(cur.amount);
                    } else {
                        dailyBalance = dailyBalance - Number(cur.amount);
                    }

                    acc[index].accounts.push({
                        account: cur.account,
                        time: cur.time,
                        category: cur.category,
                        comment: cur.comment,
                        types: cur.type_html,
                        amount: cur.amount_html,
                        balance: cur.balance,

                        dailyBalance2: dailyBalance
                    })
                } else { //new day and first
                    dailyBalance = 0.00;
                    if (cur.type == 1) {
                        dailyBalance = dailyBalance + Number(cur.amount);
                    } else {
                        dailyBalance = dailyBalance - Number(cur.amount);
                    }

                    cur.accounts = []
                    cur.accounts.push({
                        account: cur.account,
                        time: cur.time,
                        category: cur.category,
                        comment: cur.comment,
                        types: cur.type_html,
                        amount: cur.amount_html,
                        balance: cur.balance,

                        dailyBalance2: dailyBalance
                    })
                    acc.push(cur)
                }
                return acc
            }, [])
            $('div.timeline').append(_account.map(item => {
                let div = `<div class="time-label"><span class="bg-primary">${item.date} - ${item.dailyBalance2}</span></div>`
                item.accounts.forEach(_item => {
                    div += `              <div>
                ${_item.types}
                <div class="timeline-item">
                  <span class="float-right" style="padding: 5px 10px 5px 5px;">${_item.amount}</span>
                  <h3 class="timeline-header">${_item.account}</h3>
                  <div class="timeline-body"><small class="float-right">${_item.time}</small><b>${_item.category}</b><br>${_item.comment}</div>
                </div>
              </div>`
                })
                return div;
            }).join(''));
        } else {
            toastr.error('Некорректный json-ответ.');
        }
    },
    error: function() {
        toastr.error('Ошибка выполнения запроса.');
    }
});

Записи разбиты по дня (date), нужно за каждый день сложить (если type=1) или вычесть (если type=2) (amount) и вывести получившуюся сумму за день рядям с ${item.date}, сейчас ${item.dailyBalance2} выдаёт undefined
