До этого поддержка асинхронного кода была реализована намного сложнее, и его было труднее воспринимать.

В предыдущих версиях Python для этого использовались потоки или <a href="https://www.gevent.org/" class="external-link" target="_blank">Gevent</a>. Но такой код намного сложнее понимать, отлаживать и мысленно представлять.

Что касается JavaScript (в браузере и NodeJS), раньше там использовали для этой цели

Mas antes disso, controlar código assíncrono era bem mais complexo e difícil.

Nas versões anteriores do Python, você poderia utilizar threads ou <a href="http://www.gevent.org/" class="external-link" target="_blank">Gevent</a>. Mas o código é um pouco mais complexo de entender, debugar, e pensar sobre.
