Distinguish error profiles from correct ones

[SimonLab]

At the moment we are returning an object containing all the information of a profile. When there is an error (wrong url for example) we also return on object with only the url as a property. It will be nice to be able to know if a profile is correct or not. Can we add a property to the object, for example 'parse-error'.

Good question @SimonLab the "standard" way of doing this is to return error as the first parameter of the callback ...

[nelsonic]

any reason you would not simply set the error to an object e.g:

{
  "type":"parse error",
  "message":"failed to parse the profile page",
  "code":400
}

Or something like that...
then in the code that uses this module:

var LP = require('linkedin-public-profile-parser');
var url = 'https://uk.linkedin.com/in/random-profile-we-know-will-fail';
LP(url, function(err, data){
  if(err && err.code === 400) {
    errorhandler(err);
  }
 else {
  useDataForSomething(data); // what evs.
  }
})

Yes it's better to to check the error parameter of the callback and not include an error code on the data object itself. I forget for a moment that the callback manage the error. Thanks @nelsonic for the reminder.
