I have spent almost the last 24 hours trying go through countless videos and articles to wrap my head around this concept. I feel your explanation was the most in depth and simple to understand. Dropped a like and a subscribe. Please keep going. Happy Coding!!

Thanks for the good explanation of 'this' with arrow functions.

For this case, can you explain to me why the following is the Window object :

const video = {
title : 'ATitle',
play : () => {
console.log(this);
let innerFunc = () =>{
console.log(this)
}
innerFunc();
}
}

video.play(); // Window object

the play method is also using an arrow function, and therefore its a window object. but im not fully sure why thats tha case.

hello cem, i just read your articles on freecodecamp on callbacks and promises. i find your explanation is in depth and very beginner friendly at the same time. i would like to request you to come with a full tutorial series on javascript, es6 and react and nodejs if possible. this is my humble request.

Nice video but would be better proper terminology such as lexical scope for 'this' explanation was used as well as how hoisintg if affected. It's always good to learn proper teminology so someone's eyes don't pop put when they get asked proper questions at interviews.
