# Method name: currentLanguage()

# Method package: wixWindowFrontend

# Method menu location: wixWindowFrontend --> Multilingual --> currentLanguage

# Method Link: https://dev.wix.com/docs/velo/apis/wix-window-frontend/multilingual/current-language.md

# Method Description:

Sets or gets a site's current display language.

Setting the `currentLanguage` property changes a site's display language.
 The current page is reloaded in the newly set language.

 Set the current language using a 2-letter language code. The code must
 represent one of [the languages set to show on a site](https://support.wix.com/en/article/wix-multilingual-managing-languages-in-a-multilingual-site).
 You can retrieve a site's languages and corresponding language codes using
 the `siteLanguages` property.

 Getting the `currentLanguage` property gets the 2-letter language code
 of a site's current display language.
