Mr. Chidre, I would like to thank you from the bottom of my heart, for all the effort that you have done for us ! I will pray to God for your well-beeing. If you have time, I am sorry to bother you, can you please answer me very quckly theese questions, because 5 days have passed and I still cannot understand this things: 1. The big brown Object on the right size, which holds the function and prototype, this is the Main Object that you have mentioned in the previous tutorial as the object from all other Objects are beeing built, the MasterMind object ? And by pointing, it means that the memory location or object, which points to another place, it means that it holds the adress, it holds the same value, but they are not identical !? constructor points to the function, that means the constructor has the value of the function ?

Your tutorial are best of all to understand.. But I didn't understand this tutorial it is very complicate pls come with another video with this topic

More deep concept of object in JavaScript: The concept is a little bit advanced as it asks clear understanding of memory referencing probably the memory management techniques in computer architecture and operating systems also. But you tried your best to make it clear with the help of pointing arrows.

Array in JavaScript is a class or object?

Hi sir.difference between creating object using object literal notation and object literal clearly i understood by seeing your videos.But what is the difference between these two..?

constructor function

function Vehicle(make, model, color, year) {
this.make = make,
this.model = model,
this.color = color,
this.year = year,
this.getName = function () {
return this.make + " " + this.model;
}
}


var car = new Vehicle("Toyota", "Corolla", "Black");
car.make;
car.color;
car.getName();


class:

class Vehicle {
constructor(make, model, color) {
this.make = make;
this.model = model;
this.color = color;
}

getName() {
return this.make + " " + this.model;
}
}


var car = new Vehicle("Toyota", "Corolla", "Black");
car.make;
car.color;
car.getName();

Thanks in advance.
