What are the best practices for using async loops in JavaScript?

When using async loops in JavaScript, it's important to avoid blocking the event loop. Use for...of with await for sequential execution, or Promise.all for parallel execution.

Can you explain why blocking the event loop is a problem?

Blocking the event loop prevents other operations from executing, which can lead to a sluggish user experience and unresponsive applications.

What about error handling in async loops?

For error handling, wrap your await calls in try-catch blocks. This ensures that any errors are caught and handled gracefully.

Are there any performance considerations I should be aware of?

Yes, consider the number of concurrent promises you create. Too many can overwhelm the system. Use throttling techniques if necessary.
