This is JavaScript on lines one to three, we define an object that has a title and the title is JavaScript is great. And then on line six, we check if the article has an author, if it does, which it doesn't, we console log the author on line six, otherwise on line nine we console log anonymous author. So here we basically use if on line six to ask for permission. And then when we don't have that permission, we go on to say anonymous author.
