Why can't I create a closure in nodejs a module

Question

I'm trying to make the following nodejs module:

exports.method = function () {      
  var init = true;

  return function (args) {
     console.dir(args);
  };
};

But when I invoke this method I don't get console message:

require('./module.js').method({test: 1});

It returns a function instead of invoking it.

You need to execute the outer function, otherwise you're simply assigning it to exports.method.

In other words:

exports.method = function () {      
  var init = true;

  return function (args) {
     console.dir(args);
  };
}();

Note the trailing ()
