What are some performance tips for using async/await in JavaScript?
To improve performance with async/await, consider the following tips: 1. Use Promise.all for concurrent operations. 2. Avoid blocking the event loop. 3. Minimize the number of await calls in loops.
Can you explain why using Promise.all is beneficial?
Using Promise.all allows you to run multiple promises concurrently, which can significantly reduce the overall execution time compared to awaiting each promise sequentially.
What should I avoid when using async/await?
Avoid using await inside loops, as it can lead to performance bottlenecks. Instead, collect promises and use Promise.all.
Are there any tools to help analyze async/await performance?
Yes, tools like Chrome DevTools can help you analyze performance. Look for the 'Performance' tab to track async operations.
