WorkerNavigator: languages property
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since October 2017.
Note: This feature is only available in Web Workers.
The WorkerNavigator.languages read-only property
returns an array of strings 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).
Value
An array or strings.
Examples
You can run this insert a web worker:
navigator.language; // "en-US"
navigator.languages; // ["en-US", "zh-CN", "ja-JP"]
