- Created useDebouncedCallback hook for debouncing callbacks - Created useThrottledCallback hook for throttling callbacks - Created usePreventDoubleClick hook for preventing double-clicks - All hooks are properly typed and documented with examples - Components can use these hooks to prevent rapid interactions - Existing ButtonLoading component already disables buttons during loading

* Edge 3.2: Hook for throttling callback functions
|
|
* Limits execution to at most once per specified time period
|
|
*
|
|
* @param callback - The function to throttle
|
|
* @param delay - Minimum time between executions in milliseconds (default: 300ms)
|
|
* @returns Throttled callback function
|
|
*
|
|
* @example
|
|
* ```typescript
|
|
* const handleScroll = useThrottledCallback(() => {
|
|
* updateScrollPosition();
|
|
* }, 100);
|
|
*
|
|
* // Usage in scroll event
|
|
* window.addEventListener('scroll', handleScroll);
|
|
* ```
