范例

Catching an AggregateError

Promise.any([
  Promise.reject(new Error("some error")),
]).catch(e => {
  console.log(e instanceof AggregateError); // true
  console.log(e.message);                   // "All Promises rejected"
  console.log(e.name);                      // "AggregateError"
  console.log(e.errors);                    // [ Error: "some error" ]
});
					

Creating an AggregateError

try {
  throw new AggregateError([
    new Error("some error"),
  ], 'Hello');
} catch (e) {
  console.log(e instanceof AggregateError); // true
  console.log(e.message);                   // "Hello"
  console.log(e.name);                      // "AggregateError"
  console.log(e.errors);                    // [ Error: "some error" ]
}
