Как объединить 2 строки данных в одну строку?

Question

Я пытаюсь объединить 2 Line данных в одну строку для каждой строки. Например 1st row, который Green Bay Packers @ Chicago Bears строка должна содержать +3.5000 and -3.5000 данные, аналогично для Atlanta @ Minnesota строка должна содержать +46.000 and +46.000. Как мне добиться такого выхода?

Гораздо проще уменьшить массив до плоской структуры, чем создать шаблон, который отслеживает индекс.

const data = [
  { team: 'Team 1', score: 10 },
  { team: 'Team 2', score: 4 },
  { team: 'Team 3', score: -1 },
  { team: 'Team 4', score: -4 },
  { team: 'Team 5', score: 8 },
  { team: 'Team 6', score: 6 },
];

const mergeTeams = array => array.reduce((results, current, index) => {
  if (index % 2 === 0) {
    results.push(current);
  } else {
    const lastRow = results[results.length - 1];
    lastRow.team = `${lastRow.team} @ ${current.team}`;
    lastRow.awayScore = current.score;
  }
  return results;
}, []);

console.log(mergeTeams(data));
