2a. Constructor functions are used to create objects and set specified properties or initial values for that object. Function plane(new_model, new_make, new_year) { this.model = new_model; this.make = new_make; this.year = new_year; }

var my_plane = new plane("Plane", "V123", "2000");

2b. You can add a method to a Javascript object by initializing a property in the constructor that points to the method.

function display()
{
	Document.write(this.model, “<br/>”
		this.make, “<br/>”
		this.year, “<br/>”);
}

    function plane(new_model, new_make, new_year)
    {
	this.model = new_model;
	this.make = new_make;
	this.year = new_year;
	this.display = display;
    }

OR

plane.prototype.display = display;

2c. The prototype property can be used to create one pointer compared to a separate pointer for the property everytime a new object is created. Every new object will use the same pointer referenced by the prototype.

plane.prototype.display = display;

Small detail, but that very first "Function" should not be capitalized.
