What Do I Need to Know to Ace a JavaScript Interview?

Often there are threads posted around the internet about how to answer the top 10 gotcha JavaScript developer interview questions. Studying these the day before an interview is pointless like pulling an all-nighter studying for the SATs in 10th grade. We know what we know and these tests measure the culmination over the years of that knowledge. Nonetheless, I'm putting together a resource for review that covers some of the important concepts a JavaScript developer should know.

I'm reviewing material I have in my bookmark manager and listing it here.
