 <p>As soon as JavaScript executes this statement, the <code>mark</code> object also has the <code>specialty</code> property with the value of <code>"none"</code>.

 <p>So far, the constructor function has created a generic object and then specified local properties and values for the new object. You can have the constructor add more properties by directly calling the constructor function for an object higher in the prototype chain. The following figure shows these new definitions.</p>
