Throttling

Summary

A technique that limits a function to running at most once per fixed time interval, regardless of how often it's triggered — common for scroll/resize handlers. Throttling is useful when updates should continue during a burst but must be rate-limited, such as tracking scrolling or pointer movement.

• 1Implement a throttle function from scratch and apply it to a scroll listener. Validate your understanding by applying it in a small practical example.
• 2Compare debounce vs throttle behavior with a visual demo. Write down when you would choose each option and what trade-off drives that choice.
• 3Identify 2-3 real UI scenarios where throttling, not debouncing, is the right tool.
