Type: LanguageDirection (read-only)
Text direction of the site's language.
Type: Language (read-only)
Site's main language, as a 2-letter ISO 639-1 code.
On a site with Wix Multilingual, this is the main language, even when a site visitor views the site in another language.
The code has no region, so formatting dates and numbers with it alone loses regional conventions.
Use locale for formatting.
One value isn't an ISO 639-1 code: jp, a legacy code for Japanese. Intl expects ja.
Type: string (read-only)
Site's regional format, as a BCP 47 language tag.
It's the site's setting, not the site visitor's browser language. Specify it as the locale for
Intl date and number formatting, so dates and numbers follow the site's conventions for every
site visitor.
Type: string (read-only)
Site's time zone, as an IANA time zone name.
It's the time zone set for the site's business, not the site visitor's time zone. Specify it as
the timeZone option of Intl.DateTimeFormat to show times in the site's time zone.
