Async/await is a modern JavaScript feature introduced in ES2017 that allows developers to write asynchronous code in a more synchronous fashion. It helps to manage asynchronous operations more easily by using the async
keyword to declare an asynchronous function, and the await
keyword to pause the execution of the function until a Promise is resolved.
This approach improves code readability and maintainability, as it avoids the "callback hell" that often occurs with traditional Promise chaining.
async function fetchData() {
try {
const response = await fetch('https://api.example.com/data');
const data = await response.json();
console.log(data);
} catch (error) {
console.error('Error fetching data:', error);
}
}
fetchData();
