Sensible Javascript Constructors

[Jonathan Aquino]

Here's how to create a proper "constructor" in Javascript. Note that the confusing "new" operator is not required. Also "private variables" are implemented through the magic of closures.

function gizmo(id) {
return {

 id: id,

 toString: function () {

 return "gizmo " + this.id;

 }

 };

 }
