What are some alternatives to try-catch in TypeScript?

In TypeScript, you can use several alternatives to try-catch, such as using promises with .catch(), async/await with error handling, or even higher-order functions to manage errors.

Can you explain how to use promises for error handling?

Sure! When using promises, you can attach a .catch() method to handle any errors that occur during the promise execution. For example:

fetchData()
  .then(data => console.log(data))
  .catch(error => console.error('Error:', error));

What about using async/await?

With async/await, you can use a try-catch block around your await calls. Here's an example:

async function fetchData() {
  try {
    const data = await getData();
    console.log(data);
  } catch (error) {
    console.error('Error:', error);
  }
}

Are there any other patterns I should know about?

Yes! You can also use functional programming techniques, like returning error objects or using monads to handle errors more gracefully.
