This is perfect. Exactly what I needed to better understand scope. And I really appreciate how slowly and clearly you speak. Makes taking notes and processing information that much easier.

these all are function expressions, but does scope chain apply to function statements as well?

Thanks. You make yourself very clear and easy understandable. Question about global scope and websites per se. Do the global scope is limited to a web pages where the script or function was called?

When you change the last function from console.log to add10(3) you didnt log the value returned but it did log it to the console returning 13 as a result. Why was the last 13 logged to the console without using console.log?

Where should I start because I noticed that the videos are in some unsorted arrangement ! Why don’t you sort them in one playlist ??? Bit confuse !!!
