TypeScript

import a2a from 'a2a';

a2a(Promise.resolve(123)) // => Promise<[any, number]>
  .then(([error, result]) => {
    console.log(result as number);
  });

// => Promise<[any, number|string]>
a2a<number|string>(Promise.resolve('123'));

// => Promise<[any, Array<number|string>]>
a2a<number|string>([Promise.resolve('123')]);

// => Promise<[Error, number|string>>
a2a<number|string, Error>(Promise.resolve('123'));
