### Outras formas de código assíncrono

Esse estilo de usar `async` e `await` é relativamente novo na linguagem.

Mas ele faz o trabalho com código assíncrono muito mais fácil.

Essa mesma sintaxe (ou quase a mesma) foi também incluída recentemente em versões modernas do JavaScript (no navegador e NodeJS).

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