const keys = [
  [
    { on: [ 'ё', 'Ё' ], off: [ '`', '~' ], name: 'Backquote' },
    { on: [ '1', '!' ], off: [ '1', '!' ], name: 'Digit1' },
    ...
  ],
  ...
];


document.querySelector('.keyboard').innerHTML = keys.map(row => `
  <div class="row">${row.map(n => `
    <div class="key">
      <span class="${n.name} on">
        <span class="case down">${n.on[0]}</span>
        <span class="case up">${n.on[1]}</span>
      </span>
      <span class="${n.name} off">
        <span class="case down">${n.off[0]}</span>
        <span class="case up">${n.off[1]}</span>
      </span>
    </div>`).join('')}
  </div>`).join('');

Зачем вам это?
Можете использовать шаблонизаторы для удобства. Например, очень удобный и простой mustache.js.

Если вы напишите весь код в js, то конечный размер страницы не изменится. В такой оптимизации совершенно нет смысла. Вот если бы вы этот html-код подгружали с сервера аяксом, а уже затем вставляли на страницу... то тогда да, в этом был бы смысл.
