Error: Cannot call impure function during render
`Math.random` is an impure function. Calling an impure function can produce unstable results that update unpredictably when the component happens to re-render.
```
Math.random() is not called during render, and is only called during a useCallback that is called outside of the component’s render cycle:
```ts
import { useRef, useEffect, useCallback } from 'react';
export default function MyApp() {
const requestRef = useRef<number | null>(null);
const animate = useCallback((time: number) => {
// ⚠️ false positive “impure function called during render” here:
console.log(Math.random() + time);
requestRef.current = requestAnimationFrame(animate);
}, []);
// Start the render loop
useEffect(() => {
requestRef.current = requestAnimationFrame(animate);
return () => { if (requestRef.current) cancelAnimationFrame(requestRef.current); };
}, [animate]);
return null;
}
```
