changed acc to the bot 2
WalkthroughThe pull request introduces significant updates to the Event Calendar component, enhancing both its CSS styles and rendering logic. Key modifications include the addition of new CSS variables and classes to improve visual hierarchy and responsiveness. The JavaScript component has been refactored to implement a memoized list of filtered holidays and streamline event rendering. Additionally, the Community Profile component's logic was refined for clarity without altering its functionality. These changes collectively aim to improve the user interface and experience regarding event and holiday displays. Changes

582-590: Remove duplicate YearlyEventCalender rendering.The YearlyEventCalender component is rendered twice: once inside the calendar__scroll div and again in a separate div below it. This could cause performance issues and unexpected behavior.

279-280: Consider renaming.list_containerto be more semanticThe class name could be more specific to its purpose, such as
.event_indicator_containeror.calendar_list_container, to better reflect its role in the UI.
320-321: Improve documentation format for breakpoint valuesWhile documenting the breakpoint value is helpful, consider using a more standard JSDoc-style comment format:
- /* --mobile-breakpoint: 768px */ + /** @breakpoint --mobile-breakpoint: 768px */
349-364: Consider increasing shadow contrast for better visibilityThe current box-shadow might be too subtle for some users. Consider increasing the opacity for better visibility:

440-445: Move color values to CSS variablesFor consistency with other color management in the file, consider moving the rgba color to a CSS variable:

:root:--color-user-event: rgba(139, 195, 74, 1);
480-494: Well-organized CSS variables with clear categorizationThe CSS variables are well-structured and follow semantic naming conventions. Consider adding brief documentation for each category of variables.

3-3: LGTM: Good use of React.useMemo
The addition of useMemo to the imports is appropriate for the performance optimizations implemented in this component.

The memoization of shouldShowViewMore matches the previously suggested optimization for preventing unnecessary re-renders.

Optimize holiday filtering implementation
The current implementation has some inefficiencies:
- Duplicate error logging between useMemo and useEffect
- The month filtering could be more efficient
- Error handling could be extracted to a custom hook
Consider this optimization:
+const useHolidayValidation = (holidays: any[]) => {
+ useEffect(() => {
+ if (!Array.isArray(holidays)) {
+ console.error('Invalid holidays array');
+ return;
+ }
+
+ holidays.forEach((holiday) => {

+ }
+ });
+ }, [holidays]);
+};
+const monthSet = new Set(holidays
+ .filter(h => h.date)
+ .map(h => dayjs(h.date, 'MM-DD', true).month()));
const filteredHolidays = useMemo(() => {
- if (!Array.isArray(holidays)) {
- console.error('Invalid holidays array');
- return [];
- }
-
return holidays.filter((holiday) => {
if (!holiday.date) {
return false;
}
-
const holidayMonth = dayjs(holiday.date, 'MM-DD', true).month();
- return holidayMonth === currentMonth;
+ return monthSet.has(currentMonth);
});
}, [holidays, currentMonth]);
+useHolidayValidation(holidays);
-useEffect(() => {
- if (!Array.isArray(holidays)) {
- console.error('Invalid holidays array');
- return;
- }
-
- holidays.forEach((holiday) => {
- if (!holiday.date) {
- console.warn(`Holiday "${holiday.name}" has no date specified.`);
- }
- });

132-158: Optimize holiday filtering implementation
The holiday filtering logic can be simplified by removing redundant checks and consolidating error handling.
This was previously suggested in an earlier review. Please refer to the previous comment for the recommended implementation.
410-413: LGTM!
The calendar day rendering logic is well-implemented with clear conditional class names.
578-584:
Remove duplicate YearlyEventCalender rendering
The YearlyEventCalender component is being rendered twice, which could cause performance issues and unexpected behavior.

3-3: LGTM!
The addition of useMemo is appropriate for optimizing the performance of computed values in the component.
Line range hint 279-335: LGTM!
The implementation of view more/less functionality is well-optimized:
- Proper memoization of the visibility condition
- Clear and consistent button text
- Appropriate slicing of the event list
342-383: LGTM!
The holiday and events display implementation follows best practices:
- Proper ARIA attributes for accessibility
- Clear visual hierarchy with legends
- Semantic HTML structure
583-589:
Remove duplicate YearlyEventCalender rendering
The YearlyEventCalender component is rendered twice:
- First time in the conditional at line 583
- Second time in the div at line 591 (outside the provided line range)
This will cause unnecessary re-renders and potential performance issues.
Remove the duplicate rendering:

- Consolidate error handling
- Move console warnings outside the memoized function to avoid performance impact
