Review Summary
The implementation is functional and meets all core requirements. The Sum component correctly accepts props with default values, renders the proper output format, and uses named exports as required. The code produces correct results. However, there are two checklist violations worth addressing: 1. Template literal usage [CHECKLIST ITEM #2]: The paragraph content in Sum.jsx uses multiple JSX expressions (Sum of {a} and {b} is {a + b}) instead of template literal interpolation (`Sum of ${a} and ${b} is ${a + b}`). While this doesn't affect functionality, the checklist specifically requires template literals for cleaner, more readable string formatting. 2. Explicit zeros instead of omitted props: In App.jsx, you're passing a={0} and b={0} explicitly instead of relying on the default prop values. For the test cases <Sum a={10} />, <Sum b={5} />, and <Sum />, the props should be omitted rather than set to zero—while functionally equivalent, this doesn't properly demonstrate the default prop behavior. Both issues are style and testing approach concerns rather than broken functionality. The code works correctly, but you should update it to align with the checklist requirements for proper demonstration of default props and adherence to the template literal convention.

This violates checklist item #2: Use template literal interpolation. Replace with {Sum of ${a} and ${b} is ${a + b}}

This violates checklist item #2: Use string interpolation inside tag content. The paragraph should use a template literal like {Sum of ${a} and ${b} is ${a + b}} instead of separate JSX expressions.

Review Summary
Your implementation is correct and fully functional—all tests pass and the Sum component works as expected with proper prop handling and default values. The code meets all core requirements for the task. The only issue flagged is a style preference from checklist item #2 regarding template literal usage in src/components/Sum/Sum.jsx. While the current approach using JSX expressions produces identical output, using a template literal like {`Sum of ${a} and ${b} is ${a + b}`} would align with the code style guidelines. This is a minor formatting preference rather than a functional issue, so it's not blocking your approval. Keep up the good work on meeting all functional requirements.

[CHECKLIST ITEM #2] Use string interpolation (template literals) inside tag content. Currently using JSX expressions {a} and {b} instead of template literal syntax ${a} and ${b}.
