  });
}

const promises = [
  asyncTask(3),
  asyncTask(1),
  asyncTask(7),
  asyncTask(2),
  asyncTask(5),
];

asyncSeriesExecuter = async (promises)=> {
 
  for(let i=0; i<promises.length; i++) {
     await promises[i].then((data)=>{
       console.log(data)
     })
  }
 

 
}

asyncSeriesExecuter(promises);
