How can I use Promise.all in React?

You can use Promise.all to handle multiple promises in React. It takes an array of promises and resolves when all of them are fulfilled.

Can you give me an example of how to implement it?

Sure! Here's a simple example:

const fetchData = async () => {
  const [data1, data2] = await Promise.all([
    fetch('/api/data1'),
    fetch('/api/data2')
  ]);
  // Process data1 and data2
};

What happens if one of the promises fails?

If one of the promises fails, Promise.all will reject with that error, and you can handle it using a try-catch block.

Is there a way to handle individual promise failures?

Yes, you can use Promise.allSettled, which will wait for all promises to settle and return their results, regardless of success or failure.
