Update Component at certain time using React hook in ReactJs

by Abdul Rawoof A R Updated: Jan 24, 2023

In this kit, we are going to see how to update component at certain time using React Hook in ReactJs with simple steps. we declare a new state variable by calling the useState Hook. It returns a pair of values, to which we give names. The setTimeout method calls a function or runs some code after a period of time, specified using the second argument. Using setTime inside React components allows us to execute a function or some code at specific period. Make this task easier by using the kandi's ready-made code snippet below by clicking copy button and paste it in your IDE with added required library to get the output without any flaw.

    }, time);
    return ()=>{
      clearTimeout(timoutRef.current);
    }
  },[time]);
  return expired;
}

export default function App() {
  const [model, setModel] = useState({
    expiredAt: new Date().getTime() + 5000,
  });

  return <div>{expired ? <h1>Expired</h1> : <h1>Not expired</h1>}</div>;
}
