[oss92]

• Added custom error if locale is not found.
• Added English aliases
• Added alpha and alphanumeric support for Spanish, French, Portugese and Dutch.
• Sorted locales.

These could be de-duped with a loop.

var englishLocales = ['AU', 'GB', 'HK', 'IN', 'NZ', 'ZA', 'ZM'];
for (var locale, i = 0; i < englishLocales.length; i++) {
  locale = 'en-' + englishLocales[i];
  alpha[locale] = alpha['en-US'];
  alphanumeric[locale] = alphanumeric['en-US'];
}

True. 👍 Will update the commit now.

I de-duped the method with the loop you've written. @chriso
