How can I improve the performance of async functions in JavaScript?

How can I improve the performance of async functions in JavaScript?

To improve performance, consider using Promise.all for concurrent operations and avoid blocking the event loop.

What about using async/await? Does it affect performance?

Async/await can make code cleaner, but it may introduce slight overhead. Use it wisely with performance in mind.

Are there any specific patterns or best practices I should follow?

Yes, use batching for multiple async calls, and avoid unnecessary awaits in loops to enhance performance.

Can you give an example of batching async calls?

Sure! Instead of awaiting each call, collect them in an array and use Promise.all to execute them concurrently.
