JS class pattern [4]

klass4.js

// AMD module definition:
define(function (require) {

  // An instantiable class:
  var ClassName = function () {
    // All private instance data is stored in this._
    this._ = {};
    this._initialize();
  }, PROTO = ClassName.prototype;
  
  
  // A constant
  PROTO.MEANING_OF_LIFE = 42;
  
  
  // A "private" method begins with an underscore:
  PROTO._initialize = function () {
  }


  // A public method does not begin with an underscore:
  PROTO.update = function () {
  }


  return ClassName;

});

I played around with K as $, which seems less idiosyncratic, and happily it should annoy jQuery acolytes, but it felt a bit Perl-like. Currently I'm using PROTO for K — we'll see how long it lasts. I never use auto-complete and I don't mind typing shit out; I'm just trying to minimize repetitive line noise for ready readability.
