I'd do it like this:

    function Person(first, last, age) {
        this.first = first;
        this.last = last;
        this.age = age;
    }
    
    Person.prototype.full = function () {
        return this.first + " " + this.last;
    };
    
    Person.prototype.until = function (year) {
        return year - this.age;
    };

You shouldn't really put functions inside the constructor function unless you really need the closure.

Which is handy if you want private instance variables. But you're right, prototype should be the first choice, like I said, it's been a while.
