useNavigate()

useNavigate()
useNavigate() is a hook provided by React Router.

It allows us to navigate from one route to another using JavaScript.

For example, imagine we have:

/home
/about
/contact
If I want to move to /about when a button is clicked, I can use useNavigate().

import { useNavigate } from "react-router-dom";

function Home() {
  const navigate = useNavigate();

  return (
    <button onClick={() => navigate("/about")}>
      Go to About
    </button>
  );
}
export default Home;

Why do we need useNavigate()?

This was the part that helped me understand it better.Sometimes navigation should happen after some action.
For example:
After login → go to Dashboard
After form submission → go to Success page
After logout → go to Login page
After completing a quiz → go to Result page
In these situations, we don't just want a normal link.We want navigation to happen based on some logic.
That's where useNavigate() becomes useful.
Here,
const navigate = useNavigate();gives us a navigate function.
Then navigate("/about");means “Go to the /about route.”
