Bad practice

I'm not a fan of languages that don't strictly type, and I understand your discussion of scope, but I don't think it's helpful to offer a lesson where you deliberately suggest a bad practice like using the same variable name. Not useful.Not helpful.

I've followed most of the JS course and honestly, maybe you have already some experience with development. But as a noob on my side, this video was helpful. It explains clearly what's shadowing, something I didn't know as noob and thanks to it, I now know it can occurs with Javascript...

Agreed. Prior to TreeHouse I studied Ruby quite a bit on my own, but I'm still fairly new to programming. Since Ruby handles global variable declarations differently, I found the overview of this JS quirk quite helpful.

If anything, perhaps it could be more explicitly stated in the video that this is very much "DON'T DO THIS!" territory.
