How does async/await work in TypeScript for frontend development?

Async/await is a syntax in TypeScript that allows you to work with asynchronous code more easily. It makes your code look synchronous, which can improve readability.

Can you give me an example of using async/await in a fetch request?

Sure! Here's a simple example:

async function fetchData(url: string) {
    try {
        const response = await fetch(url);
        const data = await response.json();
        console.log(data);
    } catch (error) {
        console.error('Error fetching data:', error);
    }
}

This function fetches data from a given URL and logs it to the console.

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

The main benefits are improved readability and easier error handling. With async/await, you can use try/catch blocks, making it simpler to manage errors compared to chaining .then() and .catch().

Are there any drawbacks to using async/await?

One drawback is that async/await can lead to blocking if not used carefully, especially in long-running asynchronous operations. It's important to manage your async calls properly.
