res.render('post', { post: post});

Question

I don't get this code:
res.render('post', { post: post});
I know the 1st param is just connecting to the jade template but the 2nd portion 
{ post: post} 
That is where I am lost, I am not sure if that is what we are naming the variable to be used in the post jade template and connecting to the data from the post.
Here is all my code:
'use strict';
var express = require('express'),
    posts = require('./post.json');
var app = express();
app.set('view engine', 'jade');
app.set('views', __dirname + '/templates');
app.get('/', function(req, res){
    res.render('index.jade');
});
app.get('/blog/:title?', function(req,res) {
    var title = req.params.title;
    if (title === undefined) {
        res.status(503);
        res.send("This page is under construction");
    } else {
        var post = posts[title] || {};
        res.render('post', { post: post});
    }
});
app.listen(3000, function(){
    console.log("The frontend server is running on port 3000!")
});

Is this your code or did you copy it from a video?
I love node but haven't played around with the jade template.
I read that as your responding to the 'post' location with an object which has a key of post and a value of the var post.
I'm assuming render is a jade function. Objects are great ways to pass data with node because so much of it needs to be handled with json. If that is being received into a function on the front side then the object could be passed around.
