Little script to recap on this binding rules.

js_binding_rules.js

function displaySome(blah)
{
   console.log(this.blah); 
   console.log(this);
}



var blah = "suit yourself!";
var bleh = "don't leave, you lizard!";


// default binding
displaySome(bleh);

// implicit binding

var obj = 
    {
      
      blah: "party in the house, tonight!",
      func: displaySome
    }

obj.func(bleh);


// explicit binding

displaySome.call(obj,bleh);

// new binding

var fobj = new displaySome(bleh);
fobj.blah = "jerk";
