What are the best practices for error handling in JavaScript?

Some best practices include using try-catch blocks, throwing custom errors, and handling asynchronous errors properly.

Can you explain how to use try-catch blocks effectively?

Certainly! Try-catch blocks allow you to catch errors in your code. You place the code that might throw an error in the try block, and if an error occurs, the catch block will handle it.

What about handling errors in asynchronous code?

For asynchronous code, you can use try-catch with async/await or handle errors in the .catch() method of Promises.

Are there any tools or libraries that can help with error handling?

Yes, libraries like Sentry and Rollbar can help track and manage errors in your applications.
