Playing with JavaScript async await behaviour

async_await.js

async function one() {
  return 1;
}

const onePromise = one();
console.log(`one: ${onePromise}`);
onePromise.then(data => console.log(`one data: ${data}`));

async function nothing() {
  console.log('in nothing');
}

const nothingResult = nothing();
console.log(`nothing: ${nothingResult}`);
nothingResult.then(data => console.log(`nothing data: ${data}`));

const Test = {
  first: async () => {

    console.log('in first()');
    return "uno";
  },
  second: async () => {
    console.log('in second()');
    return "dos";
  },
  third: async () => {
    console.log('in third()');
    return "tres";
  }
}

async function test() {
  console.log('test a');
  const a = Test.first();
  console.log(`test a: ${a}`);
  console.log('test b');
  const b = Test.second();
  console.log(`test b: ${b}`);
  console.log('test c');
  const c = Test.third();
  console.log(`test c: ${c}`);
}

test();

async function testAwait() {
  console.log('testAwait a');
  const a = await Test.first();
  console.log(`testAwait a: ${a}`);
  console.log('testAwait b');
  const b = await Test.second();
  console.log(`testAwait b: ${b}`);
  console.log('testAwait c');
  const c = await Test.third();
  console.log(`testAwait c: ${c}`);
}

testAwait();
