Foil 13 Java vs. JavaScript II

From Overview of JavaScript I -- Basic Web Scripting Language CPS616 Technologies of the Information Age -- Spring Semester 99. by Geoffrey C. Fox (Tom Scavo)
1 Java classes and instances are distinct
2 A Java class has zero or more constructors
3 Java property inheritance follows class hierarchy
4 In Java, no way to add properties at run-time
5 JS object definition and constructor are identical and defined like methods
6 JavaScript property inheritance follows prototype chain
7 JavaScript properties may be added or removed at run-time
8 So essentially in JS, class structure is totally dynamic (a.k.a. Ill defined)
