How can I handle errors in async data fetching with React and Vue?

In React, you can use try-catch blocks in your async functions or handle errors in the component's state. In Vue, you can use the errorCaptured lifecycle hook or manage errors in your data fetching methods.

Can you give me an example of error handling in a React component?

Sure! In a React component, you might do something like this:

async function fetchData() {
  try {
    const response = await fetch('your-api-url');
    if (!response.ok) {
      throw new Error('Network response was not ok');
    }
    const data = await response.json();
    setData(data);
  } catch (error) {
    setError(error.message);
  }
}

What about in Vue? How would that look?

In Vue, you could handle errors like this:

methods: {
  async fetchData() {
    try {
      const response = await axios.get('your-api-url');
      this.data = response.data;
    } catch (error) {
      this.error = error.message;
    }
  }
}
