Promise.any is a promise combinator that resolves the resulting promise as soon as one of the input promises is fulfilled.
const promises = [
fetch('/endpoint-a').then(() => 'a'),
fetch('/endpoint-b').then(() => 'b'),
fetch('/endpoint-c').then(() => 'c'),
];
try {
const first = await Promise.any(promises);
// Any of the promises was fulfilled.
console.log(first);
// → e.g. 'b'
} catch (error) {
// All of the promises were rejected.
console.assert(error instanceof AggregateError);
// Log the rejection values:
console.log(error.errors);
}
If all input promises are rejected, the resulting promise is rejected with an AggregateError object containing an error property that holds an array of rejection values.
