Review Summary

Your solution is approved because it meets all core functional requirements: Sum is correctly implemented as a named export, defaults a and b to 0 when missing, and App renders all the required Sum combinations without breaking functionality. The only remaining issue is a style/checklist one: the text inside the <p> in src/App.jsx and src/components/Sum/Sum.jsx is currently composed from separate JSX expressions instead of a single interpolated string, which goes against [CHECKLIST ITEM #2]. For example, instead of Sum of {a} and {b} is {a + b}, the checklist expects {Sum of ${a} and ${b} is ${a + b}} inside the <p>.

This is not a functional blocker and does not prevent the task from being completed, so it doesn’t stop approval. However, to fully align with the checklist and improve readability, I recommend updating the paragraph content in Sum (and any similar usages in App.jsx) to use a single template string inside the tag. Overall, you did well on the behavior and props handling; just treat the string interpolation change as a small polish step for future submissions.

This violates checklist item #2: Use string interpolation inside tag content. Your current implementation matches the BAD EXAMPLE pattern with separate text and expressions; you should change it to the template string pattern shown in the GOOD EXAMPLE.

This violates checklist item #2: "[CODE STYLE] - Use string interpolation inside tag content". The current implementation Sum of {a} and {b} is {a + b} matches the BAD EXAMPLE pattern with separate pieces instead of a single interpolated string. Consider changing it to {Sum of ${a} and ${b} is ${a + b}} inside the <p> tag.
