You could do it this way:

example. firstAsyncRequest()
   .then(firstResponse => {
      return example.secondAsyncRequest(firstResponse)
   })
  .then(secondResponse => {
    return example.thirdAsyncRequest(secondResponse)
  })
  .then(thirdResponse => {
     // you can keep coding with sanity :)
  })

Promise are here to resolve the callback hell, no need to do it again with them ahah

Or even:

example.firstAsyncRequest()
  .then(firstResponse => example.secondAsyncRequest(firstResponse))
  .then(secondResponse => example.thirdAsyncRequest(secondResponse))
  .then(thirdResponse => {
     // you can keep coding with sanity :)
  });
