Answer 1

You can't chain comparisons like that, at least not in javascript. It probably doesn't do what you think it does; here's what happens with the first one:

We have
a < b < c

For clarity I will add parentheses
(a < b) < c

We evaluate `(a < b)`
true < c

You can't compare a bool to a number, so `true` is converted to `1`.
1 < c

That happens to be `true`.

And in the second case we end up with `true > a` which is `false`. Remember that challenge questions are often designed to fool you :P
