How to get current language from Vue component?

I made a Vue component for the panel and I was hoping to show the current language in there, something like:

export default {
  template: `<div>

Obviously, this doesn’t work, but I’ve been trying all sorts of things and I can’t find out how to get the current language. I have found out how to get the list of all languages, with this.$api.get('languages'), and that even tells me which language is the default language, but I’m not finding any way to get the current language.

Could you try following code please?
