async await fetch error in javascript

To handle errors when using async/await with the fetch() method in JavaScript, you can use a try/catch block.

Here's an example code block:

index.tsx
async function fetchData(url) {
  try {
    const response = await fetch(url);
    const data = await response.json();
    return data;
  } catch (error) {
    console.error(error);
  }
}

In the above code block, we have an async function fetchData() that takes in a URL and uses the fetch() method to make a request to the URL. Inside the try block, we await the response and parse the JSON data from the response.

If there is an error with the fetch() request, the catch block will catch the error and log it to the console using console.error(). This way, we can handle the error and prevent it from crashing the program.

Lastly, we can call the fetchData() function with a URL to fetch data and handle any errors that might occur.
