When should I use debouncing in my app?

What is debouncing and why is it important in app development?

Debouncing is a technique used to limit the rate at which a function is executed. It's important to prevent performance issues, especially in scenarios like handling user input or API calls.

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

Sure! A common example is in search input fields. If a user types quickly, debouncing can delay the search request until they stop typing, reducing unnecessary API calls.

How do I implement debouncing in JavaScript?

You can implement debouncing in JavaScript using a simple function that sets a timeout. Here's a basic example:

function debounce(func, delay) {
    let timeout;
    return function(...args) {
        clearTimeout(timeout);
        timeout = setTimeout(() => func.apply(this, args), delay);
    };
}

Are there any downsides to using debouncing?

Yes, one downside is that it can introduce a delay in user feedback, which might not be ideal in all situations. It's important to balance performance with user experience.
