Asynchronous Process inside a javascript for loop [duplicate]

Answer 1

async await is here (ES7), so you can do this kind of things very easily now.

  var i;
  var j = 10;
  for (i = 0; i < j; i++) {
    await asycronouseProcess();
    alert(i);
  }

Remember, this works only if asycronouseProcess is returning a Promise

If asycronouseProcess is not in your control then you can make it return a Promise by yourself like this

function asyncProcess() {
  return new Promise((resolve, reject) => {
    asycronouseProcess(()=>{
      resolve();
    })
  })
}

Then replace this line await asycronouseProcess(); by await asyncProcess();

Understanding Promises before even looking into async await is must (Also read about support for async await)
