React provides powerful hooks to optimize performance and manage navigation. You can use useMemo, useCallback, and useNavigate to improve your applications.

• useMemo: Memoizes a calculated value, improving performance and avoiding unnecessary recalculations.
• useCallback: Memoizes a function, preventing unnecessary recreation and improving performance.
• useNavigate: Enables programmatic navigation between routes.

Here's how you can use them:

• useMemo: Use it for expensive calculations, like calculating a value that depends on other values.
• useCallback: Use it when passing functions to child components, to prevent unnecessary re-renders.
• useNavigate: Use it to navigate to different pages, redirect users after login, or navigate back and forward.

For example, you can use useMemo to calculate a squared value:

const squaredValue = useMemo(() => {
  return count * count;
}, [count]);

You can use useCallback to memoize a function:

const handleClick = useCallback(() => {
  console.log("Button Clicked");
}, []);

You can use useNavigate to navigate to a different page:

const navigate = useNavigate();
navigate("/about");

These hooks help you build efficient and user-friendly applications. Source: https://dev.to/jayashree_a84b6eff7bc414e/react-hooks-explained-usememo-usecallback-and-usenavigate-34f4
