How to use language-tags - 5 common examples

value.forEach(function(subvalue) {
        var subtag = subvalue ? tags.type(subvalue, label) : null
        var data = subtag ? subtag.data.record.Description : null

        if (data) {
          // Fix bug in `language-tags`, where the description of a tag when
          // indented is seen as an array, instead of continued text.
          if (subtag.data.subtag === 'ia') {
            data = [data.join(' ')]
          }

          keywords = keywords.concat(
            data
              .join(' ')
              .toLowerCase()
              .split(' ')
