In MasterQuiz, the user state is constantly changing—from starting a quiz to answering questions and viewing results.
### Custom State Machines
I implemented a state machine to handle these transitions cleanly. This prevented bugs where users could skip questions or access results before finishing.
### Real-time Validation
Every answer is validated server-side to prevent cheating, using Express middleware to ensure only authorized requests are processed.
