FAQ Accordion Card (with JS)

There are a few issues which I have encountered on the js part of this challenge.

The main thing that annoyed me the most is that when you click an arrow, it shows the answer, I wanted it to behave so that if that particular answer is still showing, when you click on another question, it will automatically close on itself, and the new one would open. But it isn't doing that, any help on that end will be highly appreciated.

Another thing was adding the font-weight class .activeH didn't affect the h2 it was being added on, at all.
