Better implementation for Intl/ICU - JavaScript Fails Story

[mhf-ir]

I18n is essetial i think so:
ICU/Intl is require but there is a problem in JS word to using i18n:

• There is no valid implementation ISO for Intl. It's wired implementation for JS.
• It's not the entire ICU library it's just simple the implementation that not cover all use cases.
• There is no parser for Convert none Georgian calendar to Standard Unix time or Standard Date Object. and etc.
• Access standard CLDR data (json output: https://github.com/unicode-cldr/cldr-json). List of valid locales and currency/calendar and etc ...specs... why it's not essential part of JS core ? I donno !!!

I suggest to see PHP implementation instead of Using same problem for JS
https://www.php.net/manual/en/book.intl.php
C library:

CLDR data:
