How can I handle errors in TypeScript?

In TypeScript, you can handle errors using try-catch blocks. You can also define custom error types.

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

Sure! Here's a simple example:

function riskyFunction() {
    throw new Error('Something went wrong!');
}

try {
    riskyFunction();
} catch (error) {
    console.error(error.message);
}

What about using 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';
    }
}

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

How do I ensure type safety with errors?

You can define a specific type for your error handling functions, ensuring that you catch and handle errors appropriately.
