What is the difference between dayo and desu? I was participating in a chat
and a person said genki dayo. I am assuming that dayo and desu mean the same
thing and can be used interchangeably. Thank you.

です is polite form. だよ is casual and friendly. You shouldn't use them
interchangeably.

If you use だよ to your boss or unfamiliar people, they would think you are
rude.
