What are the best practices for using debounce and throttle in JavaScript?

Debounce and throttle are techniques to control the rate of function execution. Debounce delays execution until after a specified time has passed since the last call, while throttle ensures a function is called at most once in a specified time period.

Can you give me examples of when to use each?

Sure! Use debounce for scenarios like search input where you want to wait until the user stops typing. Use throttle for events like scrolling or resizing where you want to limit the number of times a function is called.

What libraries can help with implementing these techniques?

Popular libraries include Lodash, which has built-in debounce and throttle functions, and RxJS for reactive programming.

Are there any performance considerations I should be aware of?

Yes, using debounce and throttle can improve performance by reducing the number of function calls, but be mindful of the delay times to ensure a responsive user experience.
