Printing a whole object that's within an array.

Is there a way to print an entire object that's within an array? For example, 

var tasks = [
  {
      name: "Do homework",
      due: "01/27/2016",
      complete: false,
      assignedTo: "Dave"
  }
];

JSON.stringify([{a: 10, b: {c: 20}}])

Yes, so to log out that tasks object to the console:

console.log(JSON.stringify(tasks));

What if I wanted to return all the values from a single object instead?

The JSON.stringify method prints every object, every property name and every value within the array...I'm just trying to access one object at a time and list its values only.

Kyle Vassella You could try this:

var tasks = [
  {
      name: "Do homework",
      due: "01/27/2016",
      complete: false,
      assignedTo: "Dave"
  }
];
// loop through each task in the array
for (var i = 0 ; i<tasks.length; i++) {
    var task = tasks[i]
        // loop through each property in the task and log value
    for (var prop in task) {
        console.log(task[prop]);
    }
}
