JavaScript

function Obj(){
    this.setAProperty = function(){ 
        this.x = 5;
    }
}

var myObj = new Obj();
//Now when I call the method, "this" refers to the location, the Obj object.
myObj.setAProperty();
//x is added as a property to myObj, the place where the method was found.
alert(myObj.x); //Returns 5.
