That entirely misses the point of the question. This does not ask how to
print "John Doe" to the console. It asks how a certain bit of code
behaves. The title should help explain it: "How `this` works in
JavaScript".
And the answer is that the same function behaves differently depending on
how it's invoked. Called as a method of the object `obj.prop`, the value
of `this` is that object. When it's called as a plain function, `this`
refers to the global object.
Questions 1 and 3 had the same format.
And the entire page is, IMHO, a waste of time.
When interviewing developers, I will ask questions designed to test the
depth of their knowledge, I will ask them to describe projects and
techniques, and I will have them write out some simple code. I have two
favorite bits. First, I present a really, really horrible bit of code
and ask them to note some of the things they see wrong with it; those who
skip over the more obvious and numerous surface flaws and go directly to
the poor choice of fundamental algorithm get my attention quickly. And
second, the only thing I have at all related to trick questions is
presented precisely as such. I only use this one with candidates who
have already demonstrated that they're fairly advanced. I present this
question and then help them figure their way through it, to determine how
well they can reason about this fairly simple, but surprising result just
through discussion: "It's a somewhat surprising fact that in Javascript,
Math.min() > Math.max(). Can you think of why this might be so?"
Other than that, I make sure I avoid trick questions, and that's really
not what this one is. I've never had someone answer it without guidance,
but some people take only a nudge or two, and for others I have to spell
it out entirely. This is not a deciding factor, but does help me form an
overall impression of a candidate.
I think questions like the ones on that site are designed to mostly pull
out minutiae rather than important questions about depth of knowledge.
They're a waste.
