    console.log('hmm');
    await null;
    const b = await Promise.resolve(1);
    console.log('b', b);
    return a + b;
}

console.log('1');
const z = a().then((result) => {
    console.log('in z');

    console.log(result);
    return 5
}).then(
    (result2) => {
        console.log('and then');
        console.log(result2);
