How to get the hostname of a url in react.js?

To get the hostname of a URL in React.js, you can use the URL constructor which is built into modern browsers. Here's an example of how to extract the hostname from a URL in a React.js component:

import React, { useState } from 'react';

const App = () => {
  const [hostname, setHostname] = useState('');

  const extractHostname = (url) => {
    try {
      const parsedUrl = new URL(url);
      setHostname(parsedUrl.hostname);
    } catch (error) {
      console.error('Invalid URL syntax');
    }
  }

  // Call extractHostname with your URL
  extractHostname('https://www.example.com');

  return (
    <div>
      <h1>Hostname: {hostname}</h1>
    </div>
  );
}

export default App;

In this code snippet, we define a extractHostname function that takes a URL as input, and uses the URL constructor to parse the URL and extract the hostname. We then call this function with a sample URL (https://www.example.com) in the component. The extracted hostname is stored in the hostname state variable and displayed in the component's render method.

Please note that the URL constructor might not work well in older browsers, so make sure to check for browser compatibility if needed.
