What are the best practices for handling fetch errors in JavaScript?

When handling fetch errors, it's important to use try-catch blocks, check response status, and provide user feedback.

Can you give me an example of how to implement that?

Sure! You can use the following code:

fetch(url)
  .then(response => {
    if (!response.ok) {
      throw new Error('Network response was not ok');
    }
    return response.json();
  })
  .catch(error => {
    console.error('There has been a problem with your fetch operation:', error);
  });

What should I do if the fetch fails multiple times?

You can implement a retry mechanism with exponential backoff to handle multiple failures gracefully.

Is there a library that can help with fetch error handling?

Yes, libraries like Axios provide built-in error handling and can simplify your fetch requests.
