1. You want AI to create a TypeScript interface from a JavaScript object's structure. What should you paste into the AI to get the most accurate types?

   1. A description of what the data should look like in your own words
   2. A sample JSON object that represents the actual data your code will handle
   3. The TypeScript compiler flags you want to ignore
   4. A screenshot of the error message you received

2. What is the main drawback of using the 'any' type in TypeScript?

   1. It prevents you from using JavaScript libraries
   2. It turns off TypeScript's type checking entirely, making bugs more likely
   3. It generates documentation for your functions automatically
   4. It automatically optimizes your code for performance

3. What does the generic syntax <T extends Record<string, unknown>> mean in TypeScript?

   1. T is a special built-in TypeScript type
   2. T must be a function
   3. T must be an object with string keys and values of any type
   4. T can only be a string

4. You get a TypeScript error: 'Type X is not assignable to Y.' What can AI help you with?

   1. Running your code to see what happens
   2. Deleting the error so your code compiles
   3. Explaining why the types don't match and suggesting fixes
   4. Converting your project to Python

5. Why might AI generate incorrect types for your data?

   1. Because TypeScript has too many rules
   2. Because TypeScript cannot handle object data
   3. Because the AI is intentionally trying to mislead you
   4. Because you provided a sample that doesn't match the real data you'll process

6. What is 'type inference' in TypeScript?

   1. TypeScript automatically figuring out types based on how you use values
   2. Ignoring type errors in your code
   3. Manually writing every single type in your code
   4. Copying types from one file to another

7. You ask AI to convert a simple JavaScript function to TypeScript. What should you provide for the best result?

   1. Only the function name
   2. A list of TypeScript keywords you want to use
   3. The error messages from your last 10 projects
   4. The actual function code plus examples of the data it will process

8. A developer writes 'let data: any = getData()' instead of proper types. What's the risk?

   1. The code will automatically fix itself
   2. TypeScript will add comments to the code
   3. TypeScript won't catch errors when data is used incorrectly
   4. The website will load faster

9. What does AI do when you ask it to explain '<T>' syntax in TypeScript?

   1. It converts TypeScript to JavaScript
   2. It deletes the generics and uses 'any' instead
   3. It automatically writes the code for you without explanation
   4. It translates the technical syntax into plain English you can understand

10. When would AI-generated types be inaccurate even if the code looks correct?

    1. When the example data you provided is different from real production data
    2. When you have too many functions
    3. When your variable names are too long
    4. When you use too many comments in your code

11. What is a TypeScript interface used for?

    1. Creating visual elements on a webpage
    2. Writing loops and conditions
    3. Connecting to a database
    4. Defining the structure and types of an object

12. You paste incomplete data to AI and get types back. What might go wrong?

    1. Properties that are sometimes present in real data might be missing from the type
    2. Your code will automatically add the missing properties
    3. The AI will warn you about every possible error
    4. TypeScript will refuse to compile anything

13. Generics in TypeScript (like <T>) allow you to create what kind of code?

    1. Code that only runs once
    2. Code that deletes itself after running
    3. Reusable components that work with multiple types
    4. Code that only works with numbers

14. What information does AI need to generate a TypeScript interface from your data?

    1. A list of all TypeScript types you want to use
    2. An example of the actual data structure with realistic values
    3. Your email address
    4. The name of your project

15. What is a practical benefit of replacing 'any' types with specific types in your code?

    1. Your website will have better colors
    2. Your code will automatically work on mobile
    3. Your code will use less memory
    4. Your IDE will show you what methods and properties are available on values
