The Basics
Declare variables using
   the var keyword.
       var easy = 'absolutely',
           really = 'yes';
Global variables are
  bound implicitly.
  Usually to the window object.

     var easy = 'absolutely';

   easy === window.easy; // true
    easy === this.easy; // true
Variables cascade
  into functions.
  var easy = 'absolutely';

  function areYouSure() {
      alert( easy ); // absolutely
  }
