What is useParams

What is useParams in React.Js and React Native?

useParams is a hook provided by React Router that allows you to access the parameters of the current route. It is commonly used in React.Js and React Native applications to retrieve dynamic data from the URL.

How to use useParams?

To use useParams, you first need to import it from the ‘react-router-dom’ package. Then, you can call it inside a functional component to access the parameters of the current route. For example, if your route is ‘/users/:id’, you can use useParams to retrieve the ‘id’ parameter.

Why is useParams useful?

useParams is useful because it allows you to create dynamic and flexible routes in your React.Js and React Native applications. Instead of hardcoding URLs, you can use parameters to pass data between different components and pages.

Example of useParams in action

Here is an example of how you can use useParams in a React.Js or React Native application:

“`jsx
import { useParams } from ‘react-router-dom’;

function UserProfile() {
const { id } = useParams();

return

;
}
“`

Limitations of useParams

One limitation of useParams is that it only works with functional components. If you are using class components in your React.Js or React Native application, you will need to use other methods to access route parameters.

Conclusion

Overall, useParams is a powerful tool in React.Js and React Native for handling dynamic routing and accessing route parameters. By using useParams, you can create more flexible and dynamic applications that can adapt to different data inputs.
