 ## ✨ 1.2 Review IMDB's code
-> [!TIP]
-> When refactoring existing code there is always a risk that we introduce bugs, so it is crucial that you take precautions to reduce the risk of introducing bugs. Here are some good steps to follow which limits these risks:
-> 1. **🔍 Understand the Code**: Thoroughly read and understand the existing code.
-> 2. **📝 Plan Changes**: Outline the changes you intend to make and weigh the effort required against the benefits.
-> 3. **🧪 Create Test Scenarios**: Develop test scenarios and document their expected outcomes.
-> 4. **💻 Implement Changes**: Make the necessary code changes.
-> 5. **✅ Verify Functionality**: Ensure that your test scenarios still pass after the changes.
