Part 3
OO and Modular Code

The facilities used to create classes and to use inheritance have significantly improved in JavaScript. In addition to working with functions, you can reach for the full power of object-oriented programming when you need it. Also, modules provide a nice way to divide the code into files with cohesive code and then intermix them in a logical and meaningful fashion. In this part you’ll learn to use classes, benefit from inheritance, and use modern JavaScript modules.
