expressJs default value of title variable declaration

Question

Where does express get the default value for its title variable. My index.jade looks like the following:

    h1= title
p Welcome to #{title}

I don't quite understand where the title variable is set.

Answer 1

In your routes/index.js you will be saying

res.render('index', { title: 'Express' });

So here it will find views/index.jade put value of title variable as 'Express'.

You can say in your jade

p Welcome to #{title} from #{name}

and while renderring

res.render('index', { title: 'Express' ,name: 'myName'});

it will be converted in Welcome to Express from myName.
