How can I handle errors in TypeScript?

In TypeScript, you can handle errors using try-catch blocks, custom error classes, and type guards.

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

Sure! Here's a simple example:

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

What about creating custom error classes?

You can create a custom error class by extending the built-in Error class. Here's an example:

class CustomError extends Error {
    constructor(message: string) {
        super(message);
        this.name = 'CustomError';
    }
}

How do I use type guards for error handling?

Type guards can help you check the type of an error. For example:

if (error instanceof CustomError) {
    // Handle custom error
} else {
    // Handle other types of errors
}
