How to implement a custom hook for throttling in React Native?

Question

Accepted Answer

**useThrottle** — limit function execution frequency.

**Implementation:**
```tsx
import { useState, useEffect, useRef, useCallback } from "react";

function useThrottle<T>(value: T, delay: number): T {
  const [throttledValue, setThrottledValue] = useState(value);
  const lastExecTime = useRef(Date.now());

useEffect(() => {
    const now = Date.now();
    const timeSinceLastExec = now - lastExecTime.current;

if (timeSinceLastExec >= delay) {
      lastExecTime.current = now;
      setThrottledValue(value);
    } else {
      const timeoutId = setTimeout(() => {
        lastExecTime.current = Date.now();
        setThrottledValue(value);
      }, delay - timeSinceLastExec);

return () => clearTimeout(timeoutId);
    }
  }, [value, delay]);

return throttledValue;
}

// Throttled callback hook
function useThrottledCallback(callback: Function, delay: number) {
  const lastCallTime = useRef(0);

return useCallback((...args) => {
    const now = Date.now();
    if (now - lastCallTime.current >= delay) {
      lastCallTime.current = now;
      callback(...args);
    }
  }, [callback, delay]);
}
```
