What is debouncing in async validation?

Debouncing is a technique used to limit the rate at which a function is executed. In async validation, it helps prevent multiple validation requests from being sent in quick succession, which can overload the server.

Can you give me an example of how to implement debouncing?

Sure! You can use a debounce function that delays the execution of the validation until a specified time has passed since the last input. For example, if a user types in a form field, the validation will only trigger after they've stopped typing for 300 milliseconds.

What libraries can I use for debouncing?

You can use libraries like Lodash, which has a built-in debounce function, or you can implement your own debounce function using JavaScript's setTimeout.

Are there any downsides to using debouncing?

Yes, one downside is that it can delay feedback to the user, especially if they expect immediate validation results. It's important to find a balance.
