Can you explain the difference between Promise.all and Promise.race in React?
Sure! Promise.all
waits for all promises to resolve, while Promise.race
resolves as soon as the first promise resolves or rejects.
Can you give me an example of when to use each?
Absolutely! Use Promise.all
when you need all results, like fetching multiple resources. Use Promise.race
when you want the first result, like a timeout.
What happens if one of the promises in Promise.all fails?
If any promise in Promise.all
fails, it will reject immediately, and you won't get the results of the other promises.
Is there a way to handle errors in Promise.all?
Yes! You can use try-catch
blocks or .catch()
on the promise chain to handle errors gracefully.
