    Can someone explain how let worked with setTimeout and not var?

    Great presentation & diagrams / flow charts of complex JavaScript subject matter in bite size chunks. Look forward to the rest of your series and book. Well done.

    You did a great work. Thank you !
    The different behavior of "let" in lexical context
    is an incredible breakthrough that all Javascript-Coders
    were looking forward to since the beginning of times…. and still cannot use it
    because of the widespread use of IE on enterprises !

    Keep up the good job!

    This is an awesomely original tutorial, I just got done doing a deep dive on JS lexical and executional environments, including the "this" keyword, this definitely helped me feel confident with that new knowledge. I am interested in what other less discussed/popular topics you are going to make into tutorials. Do you get this knowledge through pure application and experience or do you have a preferred source to teach yourself these topics?
