How can I improve performance in Vue 3 using async/await?

You can enhance performance in Vue 3 by using async/await to handle asynchronous operations efficiently. This helps in managing API calls and data fetching without blocking the main thread.

Can you give me an example of using async/await in a Vue 3 component?

Sure! Here's a simple example:

<template>
  <div>{{ data }}</div>
</template>

<script>
export default {
  data() {
    return {
      data: null,
    };
  },
  async mounted() {
    this.data = await this.fetchData();
  },
  methods: {
    async fetchData() {
      const response = await fetch('https://api.example.com/data');
      return await response.json();
    },
  },
};

What are some common pitfalls when using async/await in Vue 3?

Common pitfalls include forgetting to handle errors with try/catch, not returning promises in methods, and causing unnecessary re-renders by updating state too frequently.

How does async/await compare to using Promises directly?

Async/await provides a more readable and synchronous-like structure for handling asynchronous code compared to chaining Promises, making it easier to understand and maintain.
