What are some real-world examples of throttling and debouncing?

Throttling and debouncing are techniques used in programming to control the rate of function execution. For example, in a search input field, debouncing can be used to wait until the user stops typing before sending a request to the server. This prevents multiple requests from being sent for every keystroke.

Can you give me more examples of where these techniques are applied?

Sure! Throttling is often used in scenarios like scrolling events, where you want to limit the number of times a function is called as the user scrolls. Debouncing is commonly used in form validation, where you want to wait until the user has finished typing before checking the input.

How do I implement throttling and debouncing in JavaScript?

In JavaScript, you can implement throttling using setTimeout to limit how often a function can be called. For debouncing, you can use a similar approach but reset the timer every time the function is called until the user stops.

Are there any libraries that can help with this?

Yes, libraries like Lodash provide built-in functions for both throttling and debouncing, making it easier to implement these techniques without writing the logic from scratch.
