Throttling limits function execution to occur at most once per specified time interval, preventing performance issues during continuous events. With over 25 years of experience in software development and as the creator of CoreUI, I’ve used throttling extensively for scroll handlers, mouse movement, and animation callbacks. From my expertise, the most reliable approach is tracking the last execution time and only allowing subsequent calls after the specified interval. This technique ensures consistent performance while maintaining responsiveness during high-frequency events.

Debouncing prevents excessive function calls by delaying execution until after a specified period of inactivity. As the creator of CoreUI with over 25 years of JavaScript development experience, I’ve implemented debouncing extensively in search inputs, resize handlers, and user interaction events. From my expertise, the most effective approach is creating a closure that manages a timer, clearing previous timeouts when new calls occur. This technique dramatically improves performance by ensuring functions execute only after user activity stops.
