Error types — TypeError thrown on null property access

📖 Usage Example
new URIError('malformed URI')
new EvalError('eval() misuse')

URIError and EvalError are rarely encountered but are standard Error subtypes.

TypeError on null access

Accessing a property on null throws a TypeError at runtime.

Challenge: Verify the error is thrown.

💡 Hints (1)
  • • Wrap the property access in an arrow function for toThrow().
