async-await and outer scope changes

async.md

This problem:

let mightChange = {id:1}

const doWork = async v => {
  const result1 = await doSomethingWith(mightChange);
  const result2 = await doAnotherThingWith(mightChange);   // mightChange.id might be mutated
  return doSomething(result2)
};

is the same problem as:

const doWork = async (v,cb) => {
  doSomethingWith(mightChange, (err, v) => {
    doAnotherThingWith(mightChange, (err,v) => {   // mightChange.id might be mutated
      doSomething(v,cb)
    })
  });
};
