JavaScript Scope Chains and Closures

NewCircle Instructor, Adam Breindel's goal is for you to understand scopes, scope chains, and closures. He also wants you to be able to easily and quickly explain them to other developers.

Really one of the best explanations of JS scope and closure I have seen.

Very well explained. I also appreciate that your voice as a presenter was clear and strong. Really helped.

Still one of the best explanations of closures after all these years.

Dude! This is the best presentation about Javascript I've seen in a while. It comes to prove that when you know what you are talking about you can explain it in simple terms! - Thanks! :-)

Really one of the best explanations.. loved it..

[linardzb]

very interesting presentation, any plan to make one on functions and methods?

[TheHolyReality]

Great video. The only thing that left me confused was in the last few minutes of the video. When you showed that you can see private data using Chrome developer tools (using console.dir) through Function scope tree. Does this mean that anyone can *see* what the private data is even tho they cant do anything with it?

[tarunpahuja]

Could you please tell how scope chain would look like for "module pattern .." examples. Please

[Oscar-mphw]

Great Job! Thank you for making it easier. Subscribed.

Wait, so scope chaining (the black arrows) is only possible due to the [[scope]] member? Don't think he explicitly stated this so could anyone please confirm? Otherwise my question was how do those black arrows know where to point to, etc? Is there some other back-end mechanism? or is it just because of [[scope]]?

[cupajoesir]

It was mentioned that these slides were on speaker deck. Is there a link?
