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 bem mais complexo de entender, debugar, e pensar sobre.

Nas versões anteriores do NodeJS / Navegador JavaScript, você utilizaria "callbacks". O que leva ao "inferno do callback".

Ancak bundan önce, asenkron kodu işlemek oldukça karmaşık ve zordu.

Python'un önceki sürümlerinde, threadlerı veya <a href="https://www.gevent.org/" class="external-link" target="_blank">Gevent</a> kullanıyor olabilirdin. Ancak kodu anlamak, hata ayıklamak ve düşünmek çok daha karmaşık olurdu.
