PBS 99 of X – Building with Classes Part 2: Is-A

This week Bart Busschots brings us the penultimate JavaScript installment of Programming By Stealth as he brings us part 2 of building with classes. This wraps up our third look at Object Oriented programming in JavaScript. We learn about the concept of inheritance, and how it allows us to build classes that inherit attributes and functions from parent classes. This allows us to eliminate code duplication which Bart explains is called a "bad smell". You can find Bart's tutorial shownotes at pbs.bartificer.net/pbs99.
