INTL: The best browser API you’re not using

on YouTube ↗24m

" summary

Modern browsers include the Intl API (baseline since 2017) that replaces heavy npm formatters and cuts bundle size by using built‑in formatters for dates, numbers, currencies, lists and text. It provides DateTimeFormat, RelativeTimeFormat and DurationFormat for humanized times, NumberFormat with currency/unit and accounting styles, ListFormat and PluralRules for correct grammar, a Segmenter for words/ graphemes/ sentences, and a Collator for locale-aware sorting; it supports over 7,000 locales and runs off the JS main thread.
