How is Promises.all used?

Question

Accepted Answer

Promises.all is a method that takes an array of promises and resolves when all of them have resolved or rejects if any promise fails.

It accepts an iterable (usually an array) of promises.
Returns a single Promise that resolves when all of the promises in the iterable have resolved.
If any promise rejects, the returned promise immediately rejects with that reason.
Example: Promise.all([Promise.resolve(1), Promise.resolve(2)]) resolves to [1, 2].
Example of rejection: Promise.all([Promise.resolve(1), Promise.reject('error')]) rejects with 'error'.

Accepted Answer

Promise.all() is a method in JavaScript that takes an array of promises and returns a new promise. This new promise resolves when all the promises in the input array have resolved, or rejects when any of the promises in the input array reject.
