Fun fact: if for whatever reason you ever need to stunlock a Swedish person just ask them to explain "jo" and how it's different from "ja." You're guaranteed at least a solid 30 seconds of awkward fumbling.
Ja is an affirmative response to a question (are you awake? Yes. / Är du vaken? Ja)
Jo is an affirmative that is a contradiction of a no, or a negative statement or question ("You're awake?" "No!" "Yes you are" / "Är du vaken?" "Nej!" "Jo, det är du" )
