Why do you use the ++ at 3:26, and not the +1

just confused, because tried to do index +1, but it just goes crazy. When I do the ++ everything is fine

The statement, index + 1, doesn't assign to anything. You probably mean

index = index + 1

This is assigning the value of the variable index to index + 1.

index++ is shorthand for index = index + 1
