Node.js has a simple module loading system that reduces complexity of applications and promotes code reusability. In Node.js, files and modules are in one-to-one correspondence.

For example, foo.js loads the module circle.js in the same directory:

The contents of foo.js:

var circle = require('./circle.js');
console.log( 'The area of a circle of radius 4 is ' + circle.area(4));

The contents of circle.js:

var PI = Math.PI;

exports.area = function (r) {
  return PI * r * r;
};

exports.circumference = function (r) {
  return 2 * PI * r;
};

Node.js also has an incredible community of open source developers who publish packages using npm:
