Looping through objects with names

Question

I'm trying to loop through data with node.js. I don't know how to proceed it without returning undefined errors.

JSON

{
  "task": {
    "task-1": {
      "job": "Engineer"
    },
    "task-2": {
      "job": "Developer"
    }
  }
}

What I've attempted to do

var jobs = {
  "task": {
    "task-1": {
      "job": "Engineer"
    },
    "task-2": {
      "job": "Developer"
    }
  }
};

for (var i in jobs) {
  console.log(jobs[i].job);
}

I can't seem to get it working.

Update

So you guys are saying that I should do something like this?

for (var i in jobs.task) {
  console.log(jobs.task[i].job);
}

This has nothing to do with JSON. `jobs` is a JavaScript object. Also you already seem to know how to iterate over an object since `jobs` is an object. — Felix Kling, Dec 17 '16 at 02:37

How do I get the name of that object e.g `task-1`, `task-2`? Whenever I do `jobs.task[i]` it prints out the whole object, not just the name. — mikeywikey, Dec 17 '16 at 02:48

var jobs = {
  "task": {
    "task-1": {
      "job": "Engineer"
    },
    "task-2": {
      "job": "Developer"
    }
  }
};

for (let task in jobs) {
  for (let taskNumber in jobs[task]) {
    console.log('Job: ', jobs[task][taskNumber].job)
  }
}

I'll test this out. :) – mikeywikey Dec 17 '16 at 02:34

It would probably make more sense to iterate over `jobs.task`. – Felix Kling Dec 17 '16 at 02:38
This looks terrible and is bad practice. Downvote. – Derek Pollard Dec 17 '16 at 02:40
