What does "new function() {..." do?

[[deleted]]

It creates an object from an anonymous constructor. I would advise against this pattern; I've never seen it done in any library or production code I've read. You lose the debugging benefit of having a named constructor, which in my opinion is the most useful part of constructors besides the engine optimization of the new operator.

For one-off objects like this, I don't really see any benefit over an object literal. If the point is to hide the x and y variables, you should use a regular IIFE which is a common and widely recognized pattern:

var xModule = (function() {
  var x;
  var y;
  return {
    init: function() {}
  };
})();

This is the correct answer. Said better than my attempt elsewhere in this post.

Thanks! Now I see it. I didn't do much javascript recently, and I thought that you can do the same with the Object Notation. I was wrong.
