Execute an Array of promises sequentially without using async/await

Here could be a possible option:

let p = Promise.resolve([]);
promisesArray.forEach(q => {
  p = p.then(responses => {
    //based on the nature of each q, to start execution
    //use either q().then() or q.then()
    return q().then(response => {
      //Any further logic can be here.
      console.log(response);
      return responses.concat([response]);
    })
  })
})

p.then(responses => {
  // here you have all of the responses.
})
