Se você gostaria de fazer um curso avançado-iniciante para complementar essa seção da documentação, você pode querer conferir: <a href="https://testdriven.io/courses/tdd-fastapi/" class="external-link" target="_blank">Test-Driven Development com FastAPI e Docker</a> por **TestDriven.io**.

Ese tipo de asincronía es lo que hizo popular a NodeJS (aunque NodeJS no es paralelo) y esa es la fortaleza de Go como lenguaje de programación.

Y ese es el mismo nivel de rendimiento que obtienes con **FastAPI**.
