3. useIsFirstRender()
Here is a possible implementation for the useIsFirstRender()
hook:
import { useRef } from "react";
export function useIsFirstRender(): boolean {
const isFirstRender = useRef(true);
if (isFirstRender.current) {
isFirstRender.current = false;
return true;
}
return false;
}
The hook uses the useRef
hook to store whether it is the first render or not. On the first render, isFirstRender.current
is true
, so the hook updates isFirstRender.current
to false
and returns true
. On subsequent renders, isFirstRender.current
is false
, so the hook returns false
.
