1.12 + Section:
1.13 + Description: Determining Instance Relationships
1.14 +
1.15 + This test is the same as js1_3/inherit/proto-002, except that it uses
1.16 + the builtin instanceof operator rather than a user-defined function
1.17 + called InstanceOf.
1.18 +
1.19 + This tests Object Hierarchy and Inheritance, as described in the document
1.20 + Object Hierarchy and Inheritance in JavaScript, last modified on 12/18/97

1.23 +
1.24 + This tests the syntax ObjectName.prototype = new PrototypeObject using the
1.25 + Employee example in the document referenced above.
