PR Review — Summary

• Goal: This PR updates the version to 7.6.6, adds polyfills for older browser support, and fixes some bugs.
• Risk: Medium
• Recommendation: Fix & Re-request

🔴 Critical Issues (must fix before merge)

None identified.

⚠️ Major Issues (should fix)

• [src/js/component.js:lines 98-138] — Polyfill Implementation
  Why: The polyfill for Set is implemented inline, which can lead to code duplication and maintenance challenges if needed elsewhere.
  How to fix: Consider moving the SetSham class to a separate utility module. This will make it reusable and easier to manage.
  Notes: This change will also improve code readability and maintainability.

🟡 Minor Issues (suggested)

• [src/js/utils/dom-data.js:lines 3-69] — Polyfill for WeakMap
  Why: Similar to the Set polyfill, the FakeWeakMap class is implemented inline.
  How to fix: Extract FakeWeakMap to a utility module for reuse and clarity.

• [src/js/player.js:lines 655-661] — Error Handling
  Why: The try-catch block is broad and may hide other errors.
  How to fix: Narrow the scope of the try-catch to only the specific operations that might throw (e.g., accessing certain properties).

💡 Suggestions & Improvements

• Testing: Consider adding more comprehensive tests for the polyfills to ensure they behave as expected across different environments.
• Documentation: Update the documentation to reflect the changes in polyfill usage and any potential limitations or considerations for developers.

✅ Positives

• The PR includes a test to ensure the default ID of the first player remains consistent, which is a good practice for backward compatibility.
• The changelog is updated, providing clear documentation of changes for users.

Suggested PR checklist (add these items to the PR description)

• Extract polyfills into utility modules
• Add tests for polyfill behaviors
• Narrow error handling in player.js
• Update documentation to reflect changes

---

Additional requirements & heuristics:

• Specific file references and approximate line numbers or hunk context are included.
• Unified-diff or short snippets are provided where applicable.
• The review is collaborative and educational, aiming to enable fast fixes with clear, testable changes.

PR Review — Summary

• Goal: This PR updates the version to 7.6.6, fixes bugs, and adds support for older browsers by introducing shims for Set and WeakMap.
• Risk: Medium
• Recommendation: Fix & Re-request

🔴 Critical Issues (must fix before merge)

• [src/js/component.js:lines 98-138] — Shim for Set
  Why: The shim for Set is implemented inline, which can lead to code duplication and maintenance challenges.
  How to fix: Extract the SetSham class to a separate module or utility file for reuse and clarity.
  Tests/Verification: Ensure that existing tests cover scenarios where Set is not available.

⚠️ Major Issues (should fix)

• [src/js/utils/dom-data.js:lines 3-69] — Shim for WeakMap
  Why: Similar to the Set shim, the WeakMap shim is implemented inline, which can complicate future maintenance.
  How to fix: Move the FakeWeakMap class to a separate module or utility file.
  Notes: Consider adding tests specifically for the FakeWeakMap functionality.

🟡 Minor Issues (suggested)

• [src/js/player.js:lines 655-661] — Error handling in property copying
  Why: The try-catch block is broad and may mask other issues.
  How to fix: Narrow the catch block to specific properties known to cause issues, or log unexpected errors for debugging.

💡 Suggestions & Improvements

• Consider adding unit tests for the new shims to ensure they behave as expected across different environments.
• Review the use of window and document to ensure compatibility with server-side rendering if applicable.

✅ Positives

• The changelog is updated, providing clear documentation of changes.
• The PR includes a test to verify that the default player ID remains consistent.

Suggested PR checklist (add these items to the PR description)

• Unit tests added for SetSham and FakeWeakMap.
• Ensure compatibility with server-side rendering environments.
• Review error handling in src/js/player.js for potential improvements.

---

Additional requirements & heuristics:

• Always include specific file references and approximate line numbers or hunk context.
• Where helpful, include a tiny unified-diff (diff ... block) or a short snippet that can be copy-pasted.
• If a suggestion is speculative because context is missing, prefix with "Assuming X, …".
• Provide a confidence level per major finding: High/Medium/Low.
• If multiple fixes are possible, list a recommended minimal fix and an optional larger refactor.
• If an issue touches security, mark it Critical and explain attack scenarios and remediation steps.

Tone: collaborative and educational — enable fast fixes with clear, testable changes.
