Para el "sincrónico" (contrario al "asíncrono") comúnmente también usan el término "secuencial", porque la computadora / programa sigue todos los pasos en secuencia antes de cambiar a una tarea diferente, incluso si esos pasos implican esperar.

### Concurrencia y Hamburguesas { #concurrency-and-burgers }

Esta idea de código **asíncrono** descrita anteriormente a veces también se llama **"concurrencia"**. Es diferente del **"paralelismo"**.

its value is derived from three sources:
the defaults for the Go toolchain used to build the program,
amended to match the Go version listed in `go.mod`,
and then overridden by explicit `//go:debug` lines in the program.

The [GODEBUG History](#history) gives the exact defaults for each Go toolchain version.
For example, Go 1.21 introduces the `panicnil` setting,
controlling whether `panic(nil)` is allowed;
