When should I use debouncing or throttling in my code?

When should I use debouncing or throttling in my code?

Debouncing is used when you want to limit the rate at which a function is executed, especially for events like resizing or keypresses. Throttling, on the other hand, ensures a function is called at most once in a specified time period, which is useful for events like scrolling.

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

Sure! Use debouncing for a search input field where you want to wait until the user stops typing before making an API call. Use throttling for a scroll event where you want to execute a function every 200 milliseconds as the user scrolls.

What are the performance implications of using them?

Debouncing can improve performance by reducing the number of function calls, especially in high-frequency events. Throttling can also enhance performance by ensuring that a function doesn't get called too often, which can help maintain a smooth user experience.

Are there any libraries that can help with this?

Yes, libraries like Lodash provide built-in methods for both debouncing and throttling, making it easy to implement these techniques in your code.
