Module Demonstration

circle.js

var pi = 3.14;

exports.circumference = function(radius) {
  return radius * radius * pi;
};

exports.area = function(radius) {
  return 2 * radius * pi;
};

app.js

var circle = require('./circle');

var radius = 1;
console.log("Circ. with radius = 1:", circle.circumference(radius));
console.log("Area with radius = 1:", circle.area(radius));

Thanks, Eugen! A definite schedule hasn't shaken out yet, but for now I'm aiming for a minimum of one per week.

Amazing quality! I learned all my Ruby (and Rails) from Railscasts.

This definitely can be a huge impact on the budding Nodejs community. Keep up the great work!

Ali Pour Zahmatkesh, 2 days ago:
That was great. good quality and easy to learn.

also there is a question :

what kind of module definition is better ? define in variable and then export [maybe it make some hoisting problem] or define them directly in export content , or eaven define in module.export ! which one is the best pattern to development ?

thx
