This line is doing too much at once. Especially the second = looks like a
mistyped == until you look at it more carefully. How about splitting it into two
more palatable lines:

$('enroll-content').hidden = isEnrolled;
$('unenroll-content').hidden = !isEnrolled;

I was asked to write it this way by the previous reviewer. I also think that
having two separated lines is more readable. Done.
