The browser APIs you're shipping libraries to replace with Kilian Valkhof

Killian Valkhof, creator of Polypane, walks through how locale-aware date formatting, currency formatting, the Segmenter API, and the Collator API can replace heavy npm dependencies, with support for over 7,000 locales baked right into every evergreen browser since 2017.
