How do I handle errors in JavaScript?

In JavaScript, you can handle errors using try...catch blocks. This allows you to catch exceptions and handle them gracefully.

Can you give me an example of using try...catch?

Sure! Here's a simple example:

try {
    // Code that may throw an error
    let result = riskyFunction();
} catch (error) {
    console.error('Error occurred:', error);
}

What about throwing my own errors?

You can throw your own errors using the throw statement. For example:

throw new Error('This is a custom error!');

When should I use custom errors?

Custom errors are useful when you want to provide more context about an error or when you want to differentiate between different types of errors in your application.
