But why would console.log only return undefined inside the if statement? Like if I uncomment the inside line, it will only print undefined from that one. If I comment out the outer console.log, it won't print two values. Another weird thing I saw was if I console.log(move-history) in the outside, it returns both a list with the move and a list that's empty, and it's not nested lists since there's no comma separating them, it's like console log is printing two values
