understandinges6 asynch task runner

[wd]

Hi Nicholas,

on page 162 you define your callback as

Code hier eingeben...

function (err, data) {

  if (err) {

    result = task.throw(err);

    return;

  }

 

  result = task.next(data);

  step();

}

would the following be a viable alternative?

function (err, data) {

  result = err ? task.throw(err) : task.next(data) || {done:true};

  step();

}

Best regards, Will

Hi Will,

In the case of an error you wouldn’t want to call step(), so the two functions are not equivalent.
