go-lang like pattern for cleaner error handling with async/await

error_catcher.ts

function catcher<T = any, E = Error> (
  promise: Promise<T>
): Promise<[T | undefined, E | null]> {
  return promise
    .then<[T, null]>((data: T) => [data, null])
    .catch<[undefined, E]>((err: E) => {
      return [undefined, err];
    });
}

// Example
// const [err, result] = await catcher(someFunctio())
// if (err) { ... }
