What is the difference between debounce and throttle?

Debounce and throttle are both techniques used to control the rate at which a function is executed. Debounce delays the execution until after a specified time has passed since the last event, while throttle ensures that a function is called at most once in a specified time interval.

Can you give me an example of when to use debounce?

Sure! Debounce is useful in scenarios like search input fields, where you want to wait until the user has stopped typing for a certain period before sending a request to fetch results.

And what about throttle? When should I use that?

Throttle is ideal for scenarios like scrolling or resizing events, where you want to limit the number of times a function is called while the user is actively interacting with the page.

Are there any performance implications of using these techniques?

Yes, using debounce and throttle can significantly improve performance by reducing the number of function calls, which can help prevent lag and improve user experience.
