Ways to execute a method inside a constructor

I've been struggling to find a solution to my question because most of the responses I come across are too advanced for my beginner level understanding of JavaScript.

Below is the code snippet I am working with:

function xyPoint(x, y){
    this.x = x;
    this.y = y;
    this.debugMessage = function(){
        document.getElementById("messageArea").innerHTML =
                "xyPoint(x, y) constructor called";
    };
}

My goal is to have the informative message display automatically when I create a new instance of xyPoint using the following line of code:

var myPoint = new xyPoint(10, 20);

Instead of having to manually call the debugMessage method like this:

var myPoint = new xyPoint(10, 20);
myPoint.debugMessage();

Any assistance on how to achieve this would be greatly appreciated. Thank you in advance.

Answer №1

To implement debugging messages, simply use the debugMessage function within the constructor:

function point(xCoordinate, yCoordinate){
    this.x = xCoordinate;
    this.y = yCoordinate;
    this.outputDebugMessage = function(){
        document.getElementById("messageArea").innerHTML =
                "point(x,y) constructor has been executed";
    };
    this.outputDebugMessage();
}

Answer №2

To achieve this, simply use:

let point = new Point(5, 15).displayDebug();
