We will do some legacy code refactoring kata: https://github.com/jbrains/trivia

Agenda:

- Introduction on characterization test (golden master test)
- Walk through the codes to identify some code smell
- Some demo on refactoring (I will use the Javascript codebases as many attendees from previous sessions code in Javascript)
- Pair up with someone and do hands-on exercise on refactoring
