Answer 1

This is a function that will do everything for you in one shot. Accepts AAA BBB and AAABBB with or without space.

function go_postal(){
        let postal = $("#postal").val();
        var regex = /^[A-Za-z]\d[A-Za-z][ -]?\d[A-Za-z]\d$/;
        var pr = regex .test(postal);
        if(pr === true){
            //all good          
        } else {
            // not so much
        }
    }
