AWS, JavaScript, React - Deploy Web Apps on the Cloud - Tidy the Fetch API Call

The video tutorial explains how to implement error handling in a web application using try-catch blocks. It focuses on detecting when a JSON server is not running and handling 404 errors by checking the response status. The tutorial demonstrates how to throw and catch exceptions to provide specific error messages, ensuring that users are informed of URL mistakes rather than server issues. The video concludes with testing the error handling setup and correcting the URL to ensure the website functions correctly.

What is the primary purpose of using a try-catch block when interacting with a JSON server?

• To improve the server's performance

• To handle errors and display messages to users

• To enhance the server's security

• To increase the server's storage capacity

What does the Fetch API return when a resource is not found?

• A status of 500

• A status of 200

• A status of 404

• An error message

How can you handle a 404 error in the Fetch API?

• By changing the server's IP address

• By ignoring the error

• By checking the response status and throwing an exception

• By restarting the server

What should be done before testing the error handling mechanism?

• Clear the server's cache

• Change the server's port

• Start the JSON server if it's not running

• Update the server's software

What indicates that the website is functioning correctly after fixing URL errors?

• The server logs show no errors

• The website displays a 404 error

• The website loads and allows product selection

• The server's CPU usage decreases
