Lecture 11 : Classes & Objects | JavaScript Full Course

[@shradhaKD]

Hope you enjoy learning about object oriented programming using JS ❤ Note - at 13:32 I meant to say object, not class.

[@muhammadzulqarnain2025]

#1:00:42 Here, I have to add an important point. Example #1 const person = { name: "John", country: "USA", city: 'New York', dispaly: () => { console.log(`This is ${this.name} from ${this.city}, ${this.country}`) }, } person.display() output: This is from undefined, undefined Example #2 const person2 = { name: "John", country: "USA", city: 'New York', dispaly() { console.log(`This is ${this.name} from ${this.city}, ${this.country}`) }, } person2.display() output: This is John from New York, USA In JavaScript, regular functions (like display() in the second example) have their own this binding that depends on how they are called. When we call person.display(), this inside the function refers to the person object. However, arrow functions behave differently. They don't have their own this binding, instead, they inherit it from the surrounding context where they are defined. In the first example, the arrow function is defined within the object literal. At that point, this refers to the global object (usually window in browsers). And here this.name will return an empty string because it is the windows' property which gets/sets the name of the window's browsing context. That is why the output of first example is "This is from undefined, undefined", instead of "This is undefined from undefined, undefined". So, don't use an arrow function as a method of an object. Instead, use a regular function. Thanks

[@divyanshulohani525]

I have a question at 54:50 Why do we need to create a constructor in Admin class? I am able to pass the argument of name and email without creating a constructor in Admin class and without calling the constructor using super keyword. I am new in javascript, am I missing something here ? Ex : let admin1 = new Admin("Div", "div@123");

[@AhmedRaza-ty7zq]

Awesome video😎😎👍👍

[@sandeeptanjore1253]

Once again Shradha at her best. You made this godforsaken and complicated topic very easy to understand. Wish there was another lecture just to cover errors. That said I really enjoyed this entire lecture. Took almost 2 hours to code along and follow the lecture. Very impressive!

Doubt: When we inherit we can use parent methods on objects. For example, 38:05 We used eat() on Engineer; here eat() was a Person Class Method. Bur, Later we are told that we need to use super to access Parent Class Methods?? Can you please explain this further.
