Is ` async / await ` available in Vue.js ` mounted `?

In Vue.js, async/await can be used to handle asynchronous operations, such as API requests or asynchronous functions, but it does not directly relate to the mounting process of components. Vue component mounting refers to the process of instantiating and inserting the component into the DOM. async/await can be used within component lifecycle hooks to manage asynchronous activities and ensure they are completed before proceeding. For example, if you need to fetch data from a backend API when a Vue component loads, you might use async/await within the mounted() hook. This ensures the data is fetched and ready before the component is fully rendered, avoiding rendering issues caused by unprepared data. Here is an example of using async/await within the mounted() hook to fetch data:

javascript
<template>
  <div>
    <h1>{{ userInfo.name }}</h1>
    <p>{{ userInfo.email }}</p>
  </div>
</template>

<script>
export default {
  data() {
    return {
      userInfo: {}
    };
  },
  async mounted() {
    try {
      this.userInfo = await this.fetchUserInfo();
    } catch (error) {
      console.error('Failed to fetch user info:', error);
    }
  },
  methods: {
    async fetchUserInfo() {
      const response = await fetch('/api/user');
      if (!response.ok) throw new Error('Failed to fetch');
      const data = await response.json();
      return data;
    }
  }
}
</script>

In this example, async/await is used within the mounted() hook to ensure user information is fetched from the /api/user API endpoint before rendering proceeds. This is a practical illustration of synchronizing asynchronous operations during component mounting. In summary, async/await itself is unrelated to Vue.js component mounting, but it can be applied within specific lifecycle hooks (such as created(), mounted(), or updated()) to manage and synchronize asynchronous execution.
