Professor Bungay's attempt to market two books on one flash drive to have an evolving collection of files and images was unsuccessful, so he is releasing the Javascript exercises to the public. If interested in Introduction to Biochemical Engineering and Unit Operations and Processes in Environmental Engineering please send your message to hbungay3@gmail.com.
