How do I use try-catch in Vue.js?

In Vue.js, you can use try-catch to handle errors in your methods. For example, wrap your code in a try block and catch any errors.

Can you show me a code example?

Sure! Here's a simple example:

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

What happens if an error occurs outside of the try-catch?

If an error occurs outside of the try-catch, it will not be caught, and Vue will log it to the console. You can use global error handlers for that.

How can I implement a global error handler in Vue?

You can use the errorCaptured lifecycle hook or the Vue.config.errorHandler to handle errors globally in your Vue application.
