WorkerNavigator.languages
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The WorkerNavigator.languages read-only property returns an array of DOMStrings representing the user's preferred languages. The language is described using BCP 47 language tags. In the returned array they are ordered by preference with the most preferred language first.
The value of navigator.language is the first element of the returned array.
When its value changes, as the user's preferred languages are changed a languagechange event is fired on the WorkerGlobalScope object.
The Accept-Language HTTP header in every HTTP request from the user's browser uses the same value for the navigator.languages property except for the extra qvalues (quality values) field (e.g. en-US;q=0.8).
Syntax
preferredLanguages = globalObj.navigator.languages
Examples
