Debounce and Throttle Questions

Covers the concepts, use cases, and correct implementations of debouncing and throttling functions for event handling and performance optimization. Candidates should explain the conceptual difference that debouncing delays execution until a period of inactivity while throttling limits execution to at most once per specified interval. Expect implementations using timers or timestamps in a chosen language such as JavaScript with support for common options including leading and trailing invocation, immediate execution, cancellation, configurable wait intervals, preserving context and arguments, and handling return values where applicable. Discussion should include practical use cases such as debouncing search input or resize events and throttling scroll or pointer move handlers, performance and responsiveness trade offs, edge cases with rapid repeated calls, interactions with asynchronous functions, testing approaches, and alternatives such as request animation frame or reactive programming patterns.
