JSON: Promises vs Async/Await

Can you explain the difference between Promises and Async/Await in JavaScript?

Sure! Promises are objects that represent the eventual completion or failure of an asynchronous operation. Async/Await is syntactic sugar built on top of Promises, making asynchronous code easier to read and write.

How do I convert a Promise to Async/Await?

You can use the await keyword before a Promise to pause execution until the Promise resolves. For example, const result = await fetch(url);.

Are there any advantages to using Async/Await over Promises?

Yes, Async/Await allows for cleaner and more readable code, especially when dealing with multiple asynchronous operations. It also makes error handling easier with try/catch blocks.

Can you give me an example of using both in a function?

Certainly! Here's a simple 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);
  }
}
