Walkthrough

Modified the toggleCamera function in TeamDebateRoom.tsx by changing from const to let binding and introducing an updated implementation with additional safety guards. The new implementation checks for local stream availability, logs a warning if missing, and explicitly toggles video track enabled state.

Changes

Cohort / File(s)	Summary
Camera toggle function refactor frontend/src/Pages/TeamDebateRoom.tsx	Updated toggleCamera from const to let-bound function; introduced stricter guards checking local stream availability with early return and warning log if stream is missing; added explicit video track enabled state toggling

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~15 minutes

• Areas requiring extra attention:
  • Verify the reasoning behind the double definition of toggleCamera—ensure the second definition completely replaces the first and that no reference to the initial implementation remains active
  • Confirm the guard logic correctly prevents runtime errors when local stream is undefined or null
  • Check that the warning log message is sufficiently descriptive for debugging purposes
  • Test the video track toggling behavior under conditions where videoTrack exists vs. doesn't exist to ensure the guard doesn't mask legitimate failures

Poem

🐰 A camera toggle, tightened with care,
Guards now in place, no null pointer scare!
With warning logs and early returns,
The stream stays safe, the function learns.
Debate room streams flow smooth once more,
Thanks to defenses we now restore! ✨

187-195: Remove this dead code — useCallback reassignment is an anti-pattern.

This useCallback runs on every render but its result is immediately overwritten by the reassignment at line 919. The memoization is wasted and the code is confusing.

The proper fix for the duplicate declaration error is to delete this first declaration entirely, not to change const to let. Keep only the improved implementation at lines 919–937.

-  let toggleCamera = useCallback(() => {
-    const stream = localStreamRef.current;
-    if (stream) {
-      stream.getVideoTracks().forEach((track) => {
-        track.enabled = !track.enabled;
-      });
-    }
-    setIsCameraOn((prev) => !prev);
-  }, []);

Then at line 919, declare it properly with const:

const toggleCamera = useCallback(() => {
  // ... existing improved implementation
}, []);

919-937: Improved implementation with proper guards — LGTM once declared with const.

The additional safety checks for missing stream and video track are good defensive programming. The functional update pattern that synchronizes videoTrack.enabled with the state toggle is correct.

Once the first declaration (lines 187–195) is removed, change this to use const:

-   toggleCamera = useCallback(() => {
+  const toggleCamera = useCallback(() => {
