How does async/await affect performance in Node.js?

How does async/await affect performance in Node.js?

Async/await can improve code readability and maintainability, but it may introduce some performance overhead due to additional promise handling.

Can you explain the performance trade-offs in more detail?

Certainly! While async/await simplifies asynchronous code, it can lead to slightly slower execution compared to traditional callbacks or direct promise chaining due to the overhead of creating and resolving promises.

Are there scenarios where async/await is not recommended?

Yes, in performance-critical scenarios where micro-optimizations are necessary, using callbacks or streams might be more efficient.

What are some best practices for using async/await?

Some best practices include handling errors with try/catch, avoiding blocking calls, and using it in conjunction with other asynchronous patterns when needed.
