How do I handle errors in Fetch and Axios?

What are the best practices for error handling in Fetch and Axios?

When handling errors in Fetch, you can check the response status and throw an error if it's not in the 200 range. In Axios, you can use the catch method to handle errors.

Can you show me an example of error handling in Fetch?

Sure! Here's a simple example:

fetch('https://api.example.com/data')
  .then(response => {
    if (!response.ok) {
      throw new Error('Network response was not ok');
    }
    return response.json();
  })
  .then(data => console.log(data))
  .catch(error => console.error('There was a problem with the fetch operation:', error));

What about error handling in Axios?

In Axios, you can handle errors like this:

axios.get('https://api.example.com/data')
  .then(response => console.log(response.data))
  .catch(error => {
    if (error.response) {
      console.error('Error data:', error.response.data);
    } else {
      console.error('Error message:', error.message);
    }
  });

Are there any common mistakes to avoid when handling errors?

Yes, a common mistake is not checking the response status in Fetch or not handling different types of errors in Axios. Always ensure you provide meaningful error messages.
