What are some effective error handling techniques in JavaScript?

In JavaScript, you can use try-catch blocks, promise error handling, and custom error objects for effective error handling.

Can you explain how try-catch works?

Sure! A try-catch block allows you to test a block of code for errors. If an error occurs, the catch block will handle it.

What about handling errors in asynchronous code?

For asynchronous code, you can use .catch() with promises or try-catch within async functions to handle errors.

Are there any best practices for error handling?

Yes, some best practices include logging errors, providing user-friendly messages, and avoiding silent failures.
