We have two methods for routing navigation using V6 in ReactJs, so let's go to know what are the methods:

To prevent routing transition or navigation in React JS using v6 of the React Router library, you can use the `useNavigate()` hook provided by the library. The `useNavigate()` hook returns a navigate function that you can use to navigate programmatically to a different location.

To prevent the navigation, you can call the `preventDefault()` method on the event object passed to the click handler of the button or link that triggers the navigation.

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

    event.preventDefault(); // Prevent the default navigation behavior

    // Do some validation or other logic here

    // If everything is okay, navigate to the new location

    <button onClick={handleClick}>Navigate to new location</button>

In the example above, the `handleClick()` function is called when the user clicks on the button. The `event.preventDefault()` line prevents the default navigation behavior. You can add your own validation or logic to check if the navigation should be allowed. If everything is okay, you can call the `navigate()` function to navigate to the new location. If not, you can show an error message or do something else.

If you want to prevent navigation based on some condition, you can also use the useBlocker() hook provided by the React Router library. The useBlocker() hook allows you to block or prevent navigation based on some condition.

import { useBlocker, useNavigate } from 'react-router-dom';

    // You can add your own condition to block the navigation

      return "Are you sure you want to leave?";

In the example above, the `useBlocker()` hook is called with a function that takes the location and action parameters. The function returns a string if the navigation should be blocked, or null if it should be allowed.

You can add your own condition to block the navigation. For example, you can check if the user has unsaved changes on the current page. If there are unsaved changes, you can return a string with a confirmation message asking the user if they really want to leave the page. If there are no unsaved changes, you can return null to allow the navigation.

In this way, you can prevent routing transitions or navigation in React JS using v6 of the React Router library, either by using the `preventDefault()` method and the `useNavigate()` hook, or by using the `useBlocker()` hook.

In this article, I will explain how to prevent routing transition or navigation in ReactJS using V6.
