hreflang="jv"

jv is a valid hreflang value for Javanese.

Language: Javanese (jv, ISO 639-1)

Example

<link rel="alternate" hreflang="jv" href="https://example.com/jv/" />

The code is case-insensitive for Google. The conventional spelling is a lowercase language, a title-case script and an uppercase region: jv.

Without a region, the annotation targets every Javanese speaker regardless of country. Regional versions sit next to the language-only version in one cluster.
