Answer 1

A package I found called await-to-js can also help it.

import to from 'await-to-js';

const [err, users] = await to(getUsers());
if(err) doSomething();

The idea is like Lyes CHIOUKH's method, just a wrapper. Copied the source code here.

/**
 * @param { Promise } promise
 * @param { Object= } errorExt - Additional Information you can pass to the err object
 * @return { Promise }
 */
export function to (
  promise: Promise,
  errorExt?: object
): Promise<[U | null, T | undefined]> {
  return promise
    .then<[null, T]>((data: T) => [null, data])
    .catch<[U, undefined]>((err: U) => {
      if (errorExt) {
        Object.assign(err, errorExt);
      }

      return [err, undefined];
    });
}

export default to;
