-# Data Types Practice
+# Data Types Practice: E-commerce Shopping Cart
 
 ## Instructions
 
-Imagine you are building a shopping cart. Write documentation on the data types you would need to complete your shopping experience. For each data type, explain how and why you would use it, and provide an example. The six JavaScript data types are: String, Number, Boolean, Null, Undefined, and Object.
+Imagine you are building a modern e-commerce shopping cart system. This assignment will help you understand how different JavaScript data types work together to create real-world applications.
+
+### Your Task
+
+Create a comprehensive analysis of how you would use JavaScript data types in a shopping cart application. For each of the seven primitive data types and objects, you need to:
+
+1. **Identify** the data type and its purpose
+2. **Explain** why this data type is the best choice for specific shopping cart features
+3. **Provide** realistic code examples showing the data type in action
+4. **Describe** how this data type interacts with other parts of the shopping cart
+
+### Required Data Types to Cover
+
+**Primitive Data Types:**
+- **String**: Product names, descriptions, user information
+- **Number**: Prices, quantities, tax calculations
+- **Boolean**: Item availability, user preferences, cart status
+- **Null**: Intentionally empty values (like missing discount codes)
+- **Undefined**: Uninitialized values or missing data
+- **Symbol**: Unique identifiers (advanced use)
+- **BigInt**: Large financial calculations (advanced use)
+
+**Reference Types:**
+- **Object**: Product details, user profiles, cart contents
+- **Array**: List of products, order history, categories
+
+### Example Format for Each Data Type
+
+For each data type, structure your response like this:
+
+```markdown
+## [Data Type Name]
+
+**Purpose in Shopping Cart:** [Explain what this data type does]
+
+**Why This Type:** [Explain why this is the best choice]
+
+**Code Example:**
+```javascript
+// Your realistic code example here
+```
+
+**Real-world Usage:** [Describe how this would work in practice]
+
+**Interactions:** [Explain how this data type works with others]
+```
+
+### Bonus Challenges
+
+1. **Type Coercion**: Show an example where JavaScript automatically converts between data types in your shopping cart (e.g., string "5" + number 10)
+
+2. **Data Validation**: Demonstrate how you would check if user input is the correct data type before processing
+
+3. **Performance Considerations**: Explain when you might choose one data type over another for performance reasons
+
+### Submission Guidelines
+
+- Create a markdown document with clear headings for each data type
+- Include working JavaScript code examples
+- Use realistic e-commerce scenarios in your examples
+- Explain your reasoning clearly for beginners to understand
+- Test your code examples to ensure they work correctly
 
 ## Rubric
 
-Criteria | Exemplary | Adequate | Needs Improvement
---- | --- | --- | -- |
-Data Types | All six data types are listed, explored in detail, and documented with examples | Four data types are explored with some explanation | Two data types are explored with minimal explanation |
+| Criteria | Exemplary (90-100%) | Proficient (80-89%) | Developing (70-79%) | Needs Improvement (Below 70%) |
+|----------|---------------------|---------------------|---------------------|------------------------------|
+| **Data Type Coverage** | All 7 primitive types and objects/arrays covered with detailed explanations | 6-7 data types covered with good explanations | 4-5 data types covered with basic explanations | Fewer than 4 data types or minimal explanations |
+| **Code Examples** | All examples are realistic, working, and well-commented | Most examples work and are relevant to e-commerce | Some examples work but may be generic | Code examples are incomplete or non-functional |
+| **Real-world Application** | Clearly connects each data type to practical shopping cart features | Good connection to e-commerce scenarios | Some connection to shopping cart context | Limited real-world application demonstrated |
+| **Technical Accuracy** | All technical information is correct and demonstrates deep understanding | Most technical information is accurate | Generally accurate with minor errors | Contains significant technical errors |
+| **Communication** | Explanations are clear, beginner-friendly, and well-organized | Good explanations that are mostly clear | Explanations are understandable but may lack clarity | Explanations are unclear or poorly organized |
