 This package assumes that the [`Intl`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl) global object exists in the runtime. `Intl` is present in all modern browsers (IE11+) and Node (with full ICU). The `Intl` methods we rely on are:

-2. `Intl.DateTimeFormat` for date time formatting (can be polyfilled using [Intl.js](https://github.com/andyearnshaw/Intl.js/))

 3. `Intl.PluralRules` for plural/ordinal formatting (can be polyfilled using [@formatjs/intl-pluralrules](./polyfills/intl-pluralrules.md))
