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 data fetching and rendering without blocking the UI.

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 the benefits of using async/await over Promises?

Async/await makes your code cleaner and easier to read compared to using Promises. It allows you to write asynchronous code that looks synchronous, reducing the complexity of chaining multiple .then() calls.

Are there any performance drawbacks to using async/await?

While async/await is generally efficient, excessive use can lead to performance issues if not managed properly, such as creating too many concurrent requests. It's important to balance its use with other performance optimization techniques.
