Allow editing the languages to load if loadpath is a function

It's nice that a function or promise can be passed to manage the languages and the path generation on load, but in the end all it can return is a path that will be interpolated. I would like to be able to use a function, or a path interpolation, where i can for example remove -us at the end of en-us. Since i only have a /en folder but browser language is set to en-us, and thus it tries to fetch a file that i know won't exist

You can use the fallback feature of i18next: https://www.i18next.com/principles/fallback#fallback-language

...and/or use a different load option: https://www.i18next.com/overview/configuration-options

...or simply change the served path on server side

except the fallback only applies after the failed fetch.. with config

{
    backend: {
      loadPath: './locales/{{lng}}/{{ns}}.json'
    },
    fallbackLng: 'en'
}

You may need to change the load option to "languageOnly": https://www.i18next.com/overview/configuration-options
