TS/JS general missing features

[rehberbey]

Type: Bug

I don't know if you are adding missing features manually, but you better make a system that automates it.

Even though I opened this topic under the TS/JS title, I think this topic is also valid for other languages.

// @ts-expect-error - Property 'getCanonicalLocales' does not exist on type 'typeof Intl'.(2339)
console.log(Intl.getCanonicalLocales('EN-US')); // ["en-US"]

type INTL = keyof typeof Intl;
/*
| "Collator"
| "NumberFormat"
| "DateTimeFormat" 
| "PluralRules" 
| "RelativeTimeFormat" 
| "Locale" 
| "DisplayNames" 
| "ListFormat" 
| "Segmenter"
