WEB422 course content
Organized by week. Each "week" page has a README file that describes that week's code examples.
You can browse the code online.
You can also download the repository as a zip file.
Or, you can clone the repository to your own computer.
NOTE An updated set of Code examples has replaced the old "Code Examples 2020". The old "Code Examples" has been depricated and will be removed in future versions of this course.
