What are the performance implications of using debounce vs throttle in web development?

Debounce and throttle are techniques used to control the rate of function execution. Debounce delays execution until a certain period of inactivity, while throttle ensures a function is executed at most once in a specified time frame. This can significantly impact performance, especially in scenarios like scrolling or resizing.

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

Sure! Debounce is ideal for scenarios like search input fields where you want to wait until the user stops typing before making an API call. This reduces the number of requests sent to the server.

And when should I use throttle instead?

Throttle is best used for events that fire continuously, like scrolling or window resizing. It ensures that your function runs at regular intervals, preventing performance issues from too many executions.

What are the potential downsides of using these techniques?

The downside of debounce is that it can delay the execution of a function, which might not be ideal for real-time applications. Throttle can lead to missed events if the function is not executed frequently enough.
