This kind of knowledge is acquired by reading 'Javascript the Good Parts'. It goes without saying that someone who considers themselves a good frontend engineer has read this book.

edit: I am a frontend tech lead (not even in SV!!) and my most junior engineer will answer the question correctly. I can't even fathom how one could contribute to a non-toy app without knowing this.

People tend to remember things that they do, not what they read, much less from what they hear in lecture. The odds that I'm right is high because nobody was able to answer the question satisfactorily.

I had to do a short javascript project at work and the differences between the various function invocations was one of the first things I learned. That and how to deal with the disastrous scoping issues.
