Kyle's books and lessons have been instrumental in helping me to better understand the world of JavaScript! Not to mention he provides them for free online to everyone!

If you want to destroy your nerves, just learn JavaScript. You can start using JavaScript after a couple of months, but you cant learn it for entire life! I am two years in JavaScript, and i am mad of my self because i don't know how stuff works under the hoods. But who cares… You don't need to know how mechanical parts working inside your car, but you still can be word rally champion in driving. 😀

hi is the best

This is very simple concepts but the way you are explaining making it difficult to understand..

What's the difference between and IIFE function and anonymous function?

At 10.49,…..could any one..discribe …what is going on …in that code..
My system ..is giving errors

My explanation for the last code. setTimeout is api function which belongs to browser. When we call setTimeout, it is the same to call an asnyc function. Therefore, for each run of the for loop, the program just calls setTimeout and continues to execute next run. It does not call the setTimeout callback right away. After the for loop, variable i becomes 6. Also, after for loop, callback functions in each setTimeout we already called start executing. Therefore, the result will be 6,6,6,6,6.
P/s: setTimeout second parameter indicates that a callback function will be fired after at LEAST that amount of time, not EXACTLY. For example, if second parameter of setTimeout is 2000, it guarantees that the callback will be executed after 2 second. It can be after 2.001s depending on when event loop start executing callback function.
This is just my explanation. May be right, or may be wrong or may be half and half. Feel free to correct me. I love learning from people

most of what he demo'd here could be replaced with the 'let' keyword introduced in 2015. It allows block-scope variables.

Who on earth are you having the nerve to say "you don't know JavaScript"? Do you know me, or all the JavaScript programmers out there? I don't think so. I would kindly advise you to have a more humble approach to the subject JavaScript. You are not the JavaScript God, remember that. I Have seen good people over the years disappeared because of pride and lack of humility, and they fell very deep and never came back. When I saw the title on your book, you don't know JavaScript, i think it disgusted many, but few of them had the courage to say it directly to you. You are not creating a good atmosphere when you have this attitude that you are the JavaScript God.

Why this abrupt ending 😮

(function XXX() console.log("where is the rest of this video?"))();

The video ends in the most interesting part. 🙁

very nice
