As an addition to jrburke's answer, note that you don't have to return the constructor function directly. For most useful classes you'll also want to add methods via the prototype, which you can do like this:

define('Employee', function() {
    // Start with the constructor
    function Employee(firstName, lastName) {
        this.firstName = firstName;
        this.lastName = lastName;
    }

    // Now add methods
    Employee.prototype.fullName = function() {
        return this.firstName + ' ' + this.lastName;
    };

    // etc.

    // And now return the constructor function
    return Employee;
});

In fact this is exactly the pattern shown in this example at requirejs.org.
