28. How to detect crash of a web page?

One option is to use a third-party service that monitors the availability and performance of websites. These services can send alerts when a website is down or experiencing errors.

Another way is to use window.onerror event handler to catch and log JavaScript errors and exceptions on the page. This can give us some idea about the cause of the crash. We can also use browser DevTools to look for console errors or network errors.

Additionally, we can implement a "heartbeat" mechanism which sends periodic requests to the server and notifies the user if a response is not received within a certain time frame. This can help us detect if the website is becoming unresponsive due to a crash or other technical issues.

Overall, detecting a crash of a web page could be tricky, and it's important to have a proper monitoring and error handling mechanism in place to ensure the smooth functioning of the website.
