## Edit PR Titles

* Edit the PR title to start with an emoji from <a href="https://gitmoji.dev/" class="external-link" target="_blank">gitmoji</a>.
    * Use the emoji character, not the GitHub code. So, use `🐛` instead of `:bug:`. This is so that it shows up correctly outside of GitHub, for example in the release notes.
    * For translations use the `🌐` emoji ("globe with meridians").

Como el tiempo de ejecución se consume principalmente esperando operaciones de <abbr title="Input and Output">I/O</abbr>, las llaman operaciones "I/O bound".

Se llama "asíncrono" porque la computadora / programa no tiene que estar "sincronizado" con la tarea lenta, esperando el momento exacto en que la tarea termine, sin hacer nada, para poder tomar el resultado de la tarea y continuar el trabajo.
