How do you would refactor 2 independent conditions?

I have a code that loops through all existing posts, I need to do some comprobations after pushing an array of tags, such as if the post has a locale set, if it has tags and even if it has content, etc.

  posts.map(({ node }) => {
    if (node.frontmatter.content && node.frontmatter.content.tags) node.frontmatter.content.tags.map(tag => tags.push(tag));
    if (node.frontmatter.locale) tags.push(node.frontmatter.locale);

    return Array.from(new Set(tags));
  });

It seems quite logical that it is possible to refactor those 2 conditions in something more semantic or clean, but I didn't find any solution yet.

If you also have any other advice or tip, please don't hesitate.

Thanks.
