Los programadores usan eventos de tiempo para retrasar la ejecución de cierto código, o para repetir código a un intervalo de tiempo específico. Using await pauses the execution of its surrounding async function until the promise is settled (that is, fulfilled or rejected). You can immedately schedule a whole bunch of setTimeout() calls with varying times so they will execute at the desired times in the future (other answers here illustrate how to do that).
