What is the difference between Promise.all and Promise.race in JavaScript?
An example of an AI chatbot conversation about the differences between Promise.all and Promise.race in JavaScript.
What is the difference between Promise.all and Promise.race in JavaScript?
Promise.all waits for all promises to resolve or any to reject, while Promise.race resolves or rejects as soon as one promise does.
Can you give me an example of how each works?
Sure! For Promise.all, if you have three promises that all resolve, it returns an array of their results. For Promise.race, it returns the result of the first promise that settles.
What happens if one of the promises in Promise.all rejects?
If any promise in Promise.all rejects, the entire operation is rejected immediately with that reason.
And what about Promise.race? Does it matter if one promise rejects?
In Promise.race, if a promise rejects first, it will reject the race, regardless of the other promises.
