As someone just starting with Javascript, Vance did a great job sharing his tips and tricks to debugging Javascript effectively. I left that talk feeling more comfortable in a language Im not super comfortable in.

Like Matt, I am a relative neophyte to JS. I've been almost exclusively using Sencha ExtJS framework for the past 3 years; as such, I never talk about the DOM, use prototype, Windows.whatever, or any of the other typical JS language concerns & uses. I have been using Chrome Dev Tools to help me troubleshoot what I do in ExtJS against my API and felt like I was relatively expert in its usage. After watching you wiz through the Dev Tools and build JS directly in it, I know now that I have so much more to learn. You have provided inspiration to me as I learn jQuery, Vue, & React!
