function checkNetworkStatus() {
if (navigator.onLine) {
document.getElementById(‘status’).textContent = ‘Online’;

window.addEventListener(‘offline’, checkNetworkStatus);

Network Status Checker

Status:

checkNetworkStatus();

In this example, we use JavaScript to check the network status of the user’s device. We create a simple webpage that displays whether the user is online or offline.

The JavaScript function checkNetworkStatus() is used to check the network status. It uses the navigator.onLine property to check if the user is online or offline. If the user is online, the status is set to ‘Online’. If the user is offline, the status is set to ‘Offline’.

We also use event listeners to listen for changes in the network status. When the user goes online or offline, the checkNetworkStatus() function is called to update the status on the webpage.

This simple example demonstrates how JavaScript can be used to check the network status and provide feedback to the user. It can be useful for applications that need to know whether the user is connected to the internet, such as online/offline status indicators, real-time data synchronization, or network-dependent functionality.

For more advanced applications, frameworks like React can be used to create more robust network status checkers. With React, you can create components that automatically update based on changes in the network status, providing a seamless user experience.

Overall, JavaScript provides powerful tools for checking and reacting to the network status, allowing developers to create responsive and reliable web applications.
