Мне нужен код JavaScript, чтобы посчитать, сколько раз появляется первая буква из нескольких <td>

Я хочу посчитать, сколько раз моя команда выиграла или проиграла (V или D) в каждом соревновании (LSB или TUC или JUCS), а затем отобразить результаты, разделенные результатами И соревнованием, в другой таблице с идентификатором table_resultados_gerais.

Я так долго пытался выделить первое письмо, чтобы написать эту математику, но я не смог правильно выполнить то, что хотел, может кто-нибудь мне помочь? 

<html>

<body>

    <div id="div_resultados_gerais">

                    <th colspan="3">LSB</th>
                    <th colspan="3">TUC</th>

                <tr>

Предполагая, что вы ожидаете такой результат 

{
    "LSB": {
        "V": 2,
        "D": 3
    },
    "TUC": {
        "V": 3
    },
    "JUCS": {
        "V": 1,
        "D": 1
    }
}

Который вы позже превратите в стол

Вы можете попробовать следующее 

const table = document.querySelector('#table_calendario_jogos');
    const rows = [...table.tBodies[0].rows];
    const dataset = rows.map(row => {
        const cells = [...row.cells];
        const object = {};

        object.placar = cells[4].textContent[0];
        object.competition = cells[5].textContent;

        return object
    });

    const result = dataset.reduce((accumulator, currentValue, index, array) => {
        if (!accumulator[currentValue.competition]) {
            accumulator[currentValue.competition] = array
                .filter(item => item.competition === currentValue.competition)
                .map(item => item.placar)
                .reduce((acc, val) => {
                    if (!acc[val]) {
                        acc[val] = 1;
                    } else {
                        acc[val] = acc[val] + 1;
                    }

                    return acc;
                }, {});
        }

        return accumulator;
    }, {});

    console.log(result);

    // Render result table
    const t = document.createElement('table');
    const thead = document.createElement('thead');
    const tbody = document.createElement('tbody');
    const th1 = document.createElement('th');
    const th2 = document.createElement('th');
    const th3 = document.createElement('th');

    th1.textContent = 'Placar';
    th2.textContent = 'V';
    th3.textContent = 'D';

    thead.appendChild(th1);
    thead.appendChild(th2);
    thead.appendChild(th3);

    t.appendChild(thead);

    for (const key in result) {
        const tr = document.createElement('tr');
        const td1 = document.createElement('td');
        const td2 = document.createElement('td');
        const td3 = document.createElement('td');

        td1.textContent = key;
        td2.textContent = result[key].V;
        td3.textContent = result[key].D;

        tr.appendChild(td1);
        tr.appendChild(td2);
        tr.appendChild(td3);

        tbody.appendChild(tr)

        t.appendChild(tbody);
    }

document.querySelector('#result').appendChild(t);
