A const "variable" cannot change later. Thus you must assign it a value.
But: in your method country and state, which are declared in line 13 and 14 are your result variables. So you need to declare them as var.
When having such a control flow, it is always a good idea to initialize your result variables with the outcome when nothing matches. E.g.

hi @ste5an
I thought your solution was working but not valid.
If i do this, It always puts AL as the state, regardless what is entered.
I tried this way with @Norie but i just get <none>

Thank you so much. I'm understanding it too
You don't really need to declare state but if you do you should use let to declare it rather than const.
Also, in the if/else if statements you need to repeat thisarea like this, otherwise you''ll always return 'AL'.

P.S. You might want to consider something like this to check if the areacode is in the list of areacodes for the state.
