What is async/await in JavaScript?

Can you explain what async/await is in JavaScript?

Sure! Async/await is a syntax in JavaScript that allows you to work with asynchronous code more easily. It makes your code look synchronous, which can be easier to read and maintain.

How does async/await improve code readability?

It allows you to write asynchronous code that looks like synchronous code, reducing the need for chaining promises and making it clearer to follow the flow of execution.

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

Absolutely! Here's a simple example:

async function fetchData() {
    const response = await fetch('https://api.example.com/data');
    const data = await response.json();
    return data;
}

In this example, fetchData is an async function that waits for the fetch call to complete before proceeding.

What happens if an error occurs in an async function?

If an error occurs, you can handle it using a try/catch block. For 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);
    }
}
