function useAsyncThrottler<TFn, TArgs>(fn, options): AsyncThrottler<TFn, TArgs>
Defined in: async-throttler/useAsyncThrottler.ts:44
A low-level React hook that creates an AsyncThrottler instance to limit how often an async function can execute.
This hook is designed to be flexible and state-management agnostic - it simply returns a throttler instance that you can integrate with any state management solution (useState, Redux, Zustand, Jotai, etc).
Async throttling ensures an async function executes at most once within a specified time window, regardless of how many times it is called. This is useful for rate-limiting expensive API calls, database operations, or other async tasks.
