Yes, this bothers me greatly, particularly since in 2018-19 you could throw a pebble in any direction and hit someone who knows JS/jQuery/CSS/HTML. You almost have to go out of your way to find someone who doesn’t. I’m sure this guy is great at other things but students are paying thousands of dollars for this education.
I only remember having one prof who clearly didn’t know the material. He spent most of every class just copying code onto the board by hand, then trying to talk about it a bit. I really didn’t learn much in that class. Unfortunately it was the foundational C++ class at my university and really kind of handicapped me in successive classes that were also taught in C++.
My alma mater? The University of Michigan.
