What is the purpose of async/await and try/catch in JavaScript?

Can you explain the purpose of async/await in JavaScript?

Async/await is a syntax that allows you to write asynchronous code in a more synchronous manner, making it easier to read and maintain.

How does try/catch work with async/await?

Try/catch can be used to handle errors in async functions. If an error occurs in an awaited promise, it can be caught in the catch block.

Can you give me an example of using async/await with try/catch?

Sure! Here's a simple example:

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

What happens if I don't use try/catch with async/await?

If you don't use try/catch, any error thrown in the async function will result in an unhandled promise rejection, which can crash your application.
