What are some best practices for using async libraries in JavaScript?

When using async libraries in JavaScript, consider the following best practices: 1. Use Promises for better error handling. 2. Avoid callback hell by using async/await syntax. 3. Always handle rejections to prevent unhandled promise rejections. 4. Use libraries like Axios for HTTP requests to simplify async operations.

Can you explain how async/await works?

Sure! The async/await syntax allows you to write asynchronous code that looks synchronous. You define a function as async, and within it, you can use the await keyword to pause execution until a Promise is resolved. This makes your code cleaner and easier to read.

What are some common async libraries I should know about?

Some popular async libraries include Axios for HTTP requests, Bluebird for enhanced Promise functionality, and Async.js for managing asynchronous control flow.

How do I handle errors in async functions?

You can handle errors in async functions using try/catch blocks. Wrap your await calls in a try block, and catch any errors in the catch block to handle them gracefully.
