let countDown = 0;

//calling setInterval function and the assignning interval ID.
let intervalID = setInterval(() => {
  
  //The countDown will increment by 1 after every 1000 millisecond (1 second).
  countDown++;
  console.log(countDown);

  //When countDown is equal to 10 stopping the execution (clearing the interval).
  if (countDown == 10) clearInterval(intervalID);
}, 1000);

//Define an Array
let arrayTest = ["Vidura", "Chathura", "Kasun"];

//Reading values of Array method-1
for (let index = 0; index < arrayTest.length; index++) {
  console.log(arrayTest[index]);
}

//Reading values of Array method-2
arrayTest.forEach(function (arrValue) {
  console.log(arrValue);
});

//Reading values of Array method-3
for (const arrValue of arrayTest) {
  console.log(arrValue);
}

//Reading values of Array method-4
for (const index in arrayTest) {
  console.log(arrayTest[index]);
}

//Declearing a object
const humanObject = {
  firstName: "Vidura",
  lastName: "Dananjaya",
  age: 31,
  getFullName() {
    return `${this.firstName} ${this.lastName}`;
  },
};

//Reading values of the object properties
for (const key in humanObject) {
  //Values of the object's properties
  console.log(humanObject[key]);

  //Executing functions of the object
  if (typeof humanObject[key] === "function") {
    console.log(humanObject[key]());
  }
}

I have been looking and googling but couldn't find any course or book that teaches Object-Oriented Analysis and/or Object-oriented design in Javascript or Typescript or even in pseudocode ! Any recommenations please ! Edit : I'm aware of all the excuses related to Javascript prototypal-based object.

//Constructor function for creating the object (Human).
function Human(firstName, lastName) {
  this.firstName = firstName;
  this.lastName = lastName;
  this.getFullName = function () {
    return `${this.firstName} ${this.lastName}`;
  };
}

//Creating an object (Human) using constructor function.
const humanObject = new Human("Vidura", "Dananjaya");

//Calling functions in the object (Human).
console.log(humanObject.getFullName());

//Constructor function for creating the object (Human).
function Human(firstName, lastName) {
  this.firstName = firstName;
  this.lastName = lastName;
}

//Add a function to Human prototype
Human.prototype.getFullName = function () {
  return `${this.firstName} ${this.lastName}`;
};

//Creating an object (Human) using constructor function.
const humanObject = new Human("Vidura", "Dananjaya");

//Calling the function in the object (Human).
console.log(humanObject.getFullName());
