How can I convert promises to async/await in JavaScript?

How can I convert promises to async/await in JavaScript?

You can convert promises to async/await by using the async keyword before your function and the await keyword before the promise.

Can you show me an example?

Sure! Here's a simple example:

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

What if I have multiple promises to handle?

You can use Promise.all() with async/await to handle multiple promises:

async function fetchAllData() {
    const [data1, data2] = await Promise.all([
        fetch('https://api.example.com/data1'),
        fetch('https://api.example.com/data2')
    ]);
    return [await data1.json(), await data2.json()];
}

Are there any downsides to using async/await?

One downside is that if an awaited promise rejects, it will throw an error, which you need to handle with try/catch.
