Review Summary

Decision: Request Changes

Your Sum component is implemented very well—clear, concise, and fully meets the requirements. However, the App component currently violates a core requirement and checklist item #1, which is a critical blocker.

Critical issues to fix (blockers):

• Location: src/App.jsx
  • On the five Sum renderings (likely lines where <Sum a={...} b={...} /> are declared), all instances explicitly pass both a and b. The requirements state you must render:
    1. <Sum a={2} b={3} />
    2. <Sum a={-5} b={5} />
    3. <Sum a={10} /> (omit b so it defaults to 0)
    4. <Sum b={5} /> (omit a so it defaults to 0)
    5. <Sum /> (omit both so both default to 0)
  • Why this is wrong: The task requires demonstrating defaulting behavior by omitting props, not by explicitly passing 0.
  • How to fix: Update the 3rd, 4th, and 5th instances to omit b, omit a, and omit both, respectively, as shown above.

Minor notes (non-blocking):

• Your single-line JSX formatting looks good and aligns with the checklist.

Once you adjust App.jsx to omit the props as required, you should be fully compliant. Nice work on the Sum component—just a small tweak in App to finish strong!

This violates the requirements and checklist item #1: You must render five Sum components with the following props:

• a = 2 and b = 3
• a = -5 and b = 5
• only a = 10 (b omitted, defaults to 0)
• only b = 5 (a omitted, defaults to 0)
• no props at all (both default to 0)

Currently, all Sum components are rendered with both a and b explicitly set, which does not test the defaulting behavior. You should omit the b prop for the third instance, omit the a prop for the fourth, and omit both for the fifth.

Review Summary

Decision: APPROVE

Your implementation fully meets the functional and stylistic requirements:

• Sum correctly accepts a and b, defaults both to 0 when omitted, and renders exactly: Sum of {a} and {b} is {a + b} using a single interpolation in a <p>.
• Sum is a named export, and App renders all five required usages, including the cases omitting a, b, and both.
• JSX usage is clean and on one line where appropriate, matching the checklist.

No critical blockers or discrepancies were found. Nice work—clear, idiomatic React with solid use of destructuring defaults and template literals. Keep it up!
