Listing 4.13 - Updating our display function to add a blank line - Tasks 2 & 3

Create a function to display the posts on the console.
Separate the different blog posts.

var post1;
var post2;
var post3;
var post;
var showBlog;

post1 = {
    title : "My Crazy Space Adventure",
    author : "Philae",
    created : "2015-06-21",
    body : "You will not believe where I just woke up!! Only on a comet..."
};

post2 = {
    title : "I'm Going On An Adventure!",
    author : "BB",
    created : "2012-12-12",
    body : "I'm off with some dwarves and a wizard."
};

post3 = {
    title: "We're Home",
    author: "Han",
    created: "2015-12-17",
    body: "It's been a long search but, finally, we're back on The Falcon."
};

showBlog = function () {
    console.log(post.title);
    console.log("By " + post.author + " on " + post.created);
    console.log("--------------------");
    console.log(post.body);
    console.log("--------------------");
    console.log("");
};

To use the showBlog function, assign a blog post object to the post variable first.

post = post1;
showBlog();

post = post2;
showBlog();

post = post3;
showBlog();
