How do I use async/await in React Native with TypeScript?

To use async/await in React Native with TypeScript, you first need to define your function as async. For example:

const fetchData = async () => {
    try {
        const response = await fetch('https://api.example.com/data');
        const data = await response.json();
        console.log(data);
    } catch (error) {
        console.error('Error fetching data:', error);
    }
};

Can you explain how error handling works with async/await?

Certainly! Error handling in async/await is done using try/catch blocks. If an error occurs in the await expression, it will be caught in the catch block, allowing you to handle it gracefully.

What are the benefits of using async/await over Promises?

Async/await makes your asynchronous code look more like synchronous code, which improves readability and maintainability. It also helps avoid callback hell.

Are there any performance considerations I should be aware of?

While async/await is generally efficient, excessive use of it can lead to performance issues if not managed properly, especially in tight loops. Always consider the context of your async operations.
