I tried foreign YouTuber's courses for JavaScript but none of them could explain like you do.
To be honest it is very rare for me to comment on a video like this.
But honestly man this needs some appreciation.
You're doing great.
I hope you get successful in your YouTube journey.
Also you've provided subtitles in English.
Mad respect man.
I would suggest you to translate and upload these videos in English and other languages too, to get global audience.

The third difference between var and let is that, a variable declared with "var" can be redeclared but with "let" we can't redeclare a variable in the same scope or block.

I had watched so many videos for the javascript course but your lecture among them is one of the best i can say. I highly recommend your lectures to one who is starting with the programming and want to be pro in it. Also there are answers to the questions that were asked in the interviews, that adds a advantage to this tutorial. Thank you so much for this Javascript course. Looking forward to learn more with this series.
