WHAT’s the difference between using OR in a WHERE clause vs using IN (set)?

you mentioned that indexes are terrible at ORs but are they also terrible with IN (set)?



There seems to be a bug when you try and get the solution to this exercise: none of the buttons work in the code ‘differ’ screen. I can’t even scroll down to see the solution because the scroll doesn’t work either. I don’t know if this is a problem with my computer or a bug in the exercise, but it is very frustrating as it means I can’t complete this section.

It would be great if you could help.
