Practically the feature is done,

• if no fallbackLocales is passed we look the cldr parent locale of each locale in config file, and we create our own fallbackLocales through locales array
• if fallbackLocales.default is passed we just use that :)
• if fallbackLocale (deprecated), we create an object of fallbackLocales.default with that locale

I think all the cases are covered, I'm a bit tired now so probably something is not correct, I'll take a better look tomorrow

[semoal]

I'll do some extra testing on a sample project, to check 100% if all the cases are covered and we're ready to

Tested on create-react-app of examples folder adding ES-MX and ES, translating some things in "es", appears in es-mx 👍🏻

So I think, it works as intended

Looking good, great work! Just a few comments bellow, but this is going to be a huge improvement 👍

I am trying to use fallbackLocales and getting error

● Validation Warning:

  Unknown option "fallbackLocales" with value {"default": "en", "ps": ["en"]} was found. Did you mean "fallbackLocale"?
  This is probably a typing mistake. Fixing it will remove this message.

What is the correct way now to use it?

[MartinCerny-awin]

Ok, I guess I am reading the latest docs for unreleased version

[tricoder42]

@MartinCerny-awin Yes, sorry, there's currently a problem with latest release of docs... It'll be fixed early next week with new release setup
