| 10 Description: new PrototypeObject | |
| 11 | |
| 12 This tests Object Hierarchy and Inheritance, as described in the document | |
| 13 Object Hierarchy and Inheritance in JavaScript, last modified on 12/18/97 | |
| 14 15:19:34 on http://devedge.netscape.com/. Current URL: | |

| 16 | |
| 17 This tests the syntax ObjectName.prototype = new PrototypeObject using the | |
| 18 Employee example in the document referenced above. | |
| 19 | |
| 20 If you add a property to an object in the prototype chain, instances of | |
| 21 objects that derive from that prototype should inherit that property, even | |
| 22 if they were instatiated after the property was added to the prototype object. | |
