What are the best practices for building asynchronous applications?

When building asynchronous applications, it's crucial to manage concurrency effectively, use proper error handling, and ensure that your application remains responsive. Would you like to dive deeper into any specific area?

Yes, can you explain how to handle errors in asynchronous code?

Certainly! In asynchronous code, you can handle errors using try-catch blocks with async/await or by using .catch() with Promises. It's important to log errors and provide user-friendly messages.

What about performance optimization?

For performance optimization, consider using techniques like batching requests, caching responses, and minimizing the number of asynchronous calls. This can significantly improve the responsiveness of your app.

Are there any tools you recommend for testing asynchronous applications?

Yes! Tools like Jest, Mocha, and Cypress are great for testing asynchronous applications. They provide features to handle promises and async functions effectively.
