You can create your custom dictionary and set it as your vocabularies in your app. Dictionary is a JavaScript object that you can implement with different terms and languages.

const dict = {
    'fr': {
        'Sign In': "Se connecter",
        'Sign Up': "S'inscrire"
    },
    'es': {
        'Sign In': "Registrarse",
        'Sign Up': "Regístrate"
    }
};

I18n.putVocabularies(dict);

Retrieves a phrase from the dictionary for the active language. If the phrase does not have an entry in dictionary, the original parameter value will be returned.

I18n.get('Sign In');
