Development Notes

Account class

First use Typescript discriminated unions to represent the various type of accounts. Then show how to refactor using classes.

Lesson scheduling

Show how to program by wishful thinking by writing the code (even with errors) that you would like to use. Then glue the code using interfaces, delete all the pseudo-code and start writing tests.
