Can you explain try-catch in Vue 3 with examples?

Can you explain try-catch in Vue 3 with examples?

Sure! In Vue 3, try-catch is used to handle errors in asynchronous code. For example, you can wrap your API calls in a try-catch block to manage errors gracefully.

Can you show me a code example?

Absolutely! Here's a simple example:

async fetchData() {
  try {
    const response = await axios.get('https://api.example.com/data');
    this.data = response.data;
  } catch (error) {
    console.error('Error fetching data:', error);
  }
}

What happens if an error occurs outside the try block?

If an error occurs outside the try block, it won't be caught by the catch statement. You would need to handle it separately.

Are there any best practices for using try-catch in Vue 3?

Yes! It's best to keep your try-catch blocks as specific as possible, only wrapping the code that might throw an error, and to log errors for debugging.
