Async vs Sync Error Handling in JavaScript

What are the main differences between async and sync error handling in JavaScript?

In JavaScript, sync error handling uses try/catch blocks, while async error handling often involves promises and async/await.

Can you give me an example of async error handling?

Sure! Here's an example:

async function fetchData() {
  try {
    const response = await fetch('https://api.example.com/data');
    const data = await response.json();
    return data;
  } catch (error) {
    console.error('Error fetching data:', error);
  }
}

How does the try/catch work in synchronous code?

In synchronous code, try/catch wraps the code that might throw an error. If an error occurs, control jumps to the catch block.

Which method is preferred for error handling in modern JavaScript?

Async error handling with promises and async/await is generally preferred for better readability and handling of asynchronous operations.
