formatCurrency
Returns a localized currency value. This function behaves like the standard `Intl.NumberFormat()` with a style of `currency` applied. It uses the buyer's locale by default.
```
(number: number | bigint, options?: { inExtensionLocale?: boolean; } & NumberFormatOptions) => string
```
formatDate
Returns a localized date value. This function behaves like the standard `Intl.DateTimeFormatOptions()` and uses the buyer's locale by default. Formatting options can be passed in as options.
```
(date: Date, options?: { inExtensionLocale?: boolean; } & DateTimeFormatOptions) => string
```
formatNumber
Returns a localized number. This function behaves like the standard `Intl.NumberFormat()` with a style of `decimal` applied. It uses the buyer's locale by default.
```
(number: number | bigint, options?: { inExtensionLocale?: boolean; } & NumberFormatOptions) => string
```
translate
Returns translated content in the buyer's locale, as supported by the extension. - `options.count` is a special numeric value used in pluralization. - The other option keys and values are treated as replacements for interpolation. - If the replacements are all primitives, then `translate()` returns a single string. - If replacements contain UI components, then `translate()` returns an array of elements.
