How does async/await improve asynchronous programming?
Asked on Jul 13, 2024
Answer
Async/await simplifies asynchronous programming by making asynchronous code look and behave like synchronous code, improving readability and maintainability. Here's a basic example of how async/await is used:
<!-- BEGIN COPY / PASTE -->
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();
<!-- END COPY / PASTE -->Additional Comment:
✅ Answered with JavaScript best practices.- The "async" keyword before a function declaration allows the use of "await" inside the function.
- "await" pauses the function execution until the Promise is resolved, making the code easier to read.
- Error handling is simplified with try/catch blocks, similar to synchronous code.
- Async/await is built on top of Promises and does not block the main thread.
