What are the differences between Promises and Async/Await in Vue 3?

In Vue 3, Promises and Async/Await are both used for handling asynchronous operations, but they have different syntax and readability. Promises use .then() and .catch() methods, while Async/Await allows you to write asynchronous code that looks synchronous, making it easier to read and maintain.

Can you give me an example of using Async/Await in a Vue 3 component?

Sure! Here's a simple example:

export default {
  data() {
    return { data: null };
  },
  async mounted() {
    try {
      const response = await fetch('https://api.example.com/data');
      this.data = await response.json();
    } catch (error) {
      console.error('Error fetching data:', error);
    }
  }
};

What about error handling in Promises versus Async/Await?

In Promises, you handle errors using .catch(), while in Async/Await, you typically use a try...catch block. This makes error handling in Async/Await more straightforward and similar to synchronous code.

Which one is recommended for new Vue 3 projects?

Async/Await is generally recommended for new Vue 3 projects due to its cleaner syntax and better readability, especially when dealing with multiple asynchronous operations.
