All that is what powers FastAPI (through Starlette) and what makes it have such an impressive performance.

You can probably skip this.

These are very technical details of how **FastAPI** works underneath.

Todo eso es lo que impulsa FastAPI (a través de Starlette) y lo que hace que tenga un rendimiento tan impresionante.
