22# Comment Your Code
## Instructions
Clean, well-documented code is essential for maintaining and sharing your projects. In this assignment, you'll practice one of the most important habits of professional developers: writing clear, helpful comments that explain your code's purpose and functionality.
Go over your current `app.js` file in your game folder, and find ways to comment it and tidy it up. It's very easy for code to get out of control, and now's a good chance to add comments to ensure that you have readable code so that you can use it later.
**Your task includes:**
- **Add comments** explaining what each major section of code does
- **Document functions** with clear descriptions of their purpose and parameters
- **Organize code** into logical blocks with section headers
- **Remove** any unused or redundant code
- **Use consistent** naming conventions for variables and functions
## Rubric
| Criteria | Exemplary | Adequate | Needs Improvement |
| -------- | --------- | -------- | ----------------- |
| **Code Documentation** | `app.js` code is fully commented with clear, helpful explanations for all major sections and functions | `app.js` code is adequately commented with basic explanations for most sections | `app.js` code has minimal comments and lacks clear explanations |
| **Code Organization** | Code is organized into logical blocks with clear section headers and consistent structure | Code has some organization with basic grouping of related functionality | Code is somewhat disorganized and difficult to follow |
| **Code Quality** | All variables and functions use descriptive names, no unused code, follows consistent conventions | Most code follows good naming practices with minimal unused code | Variable names are unclear, contains unused code, inconsistent style |
