Review Summary

I’m requesting changes due to a critical checklist violation that blocks acceptance. In src/components/Sum/Sum.jsx, the paragraph currently renders as separate text and JSX nodes: Sum of {a} and {b} is {a + b} (see the line where the <p> is returned). This violates [CHECKLIST ITEM #2] which requires the paragraph content to be a single interpolated string expression. Please update that line to use template interpolation, for example: <p>{Sum of ${a} and ${b} is ${a + b}}</p>. This will produce the identical output while satisfying the required style rule.

Everything else looks solid: the component uses named export, defaults a and b to 0, and the App renders the five required cases with passing tests. Once the interpolation format is fixed, this should be good to approve. Keep up the good work!

Review Summary

I’m requesting changes due to a critical runtime blocker in the Cypress support files.

• Critical issue: In cypress/support/commands.js, the declare global { ... } block (e.g., lines containing declare global and login(email: string, password: string): Chainable<void>) uses TypeScript-only syntax in a .js file. This will throw a syntax error when Node/Cypress loads the file and break both cypress/support/component.js and cypress/support/e2e.js which import it.
• Why it’s wrong: JavaScript does not support declare or type annotations; support files must be valid JavaScript to run. This violates the requirement that tests/support code run without runtime errors.
• How to fix:
  1. Quick fix: comment out or remove the entire declare global { ... } block in cypress/support/commands.js.
  2. Alternative: move the type declarations into a new cypress/support/commands.d.ts file and keep commands.js pure JS.
  3. Or convert commands.js to TypeScript (commands.ts) and configure Cypress/Node to handle TS.

What’s good: The Sum component and App meet all functional requirements and the tests look correct. After resolving the commands file, your Cypress support imports should load and tests should run. Great work overall—this is a small but important fix to unblock CI/tests.

This line imports ./commands. Currently that file contains a declare global { ... } block and TypeScript type annotations which are invalid in a plain JavaScript file — importing it will cause a syntax error at runtime. Fix options:

• Remove or comment out the declare global / type-annotation block in cypress/support/commands.js.
• Or convert cypress/support/commands.js to TypeScript (rename to .ts/.d.ts) and adjust project config so TS files are supported.
• Alternatively, move only the type declarations into a separate .d.ts file and keep commands.js pure JS.

See the problematic content in cypress/support/commands.js for details 【}.
