How do I select ALL objects on canvas one by one with fabric js?

Question

How would the code look like to select all objects currently on a canvas one by one using fabric js. I am trying to list the attributes of each object one by one without knowing how many objects (if any) will be on the canvas.

For clarification:

Here is a https://jsfiddle.net/3bxLmwzk/

var canvas = new fabric.Canvas('canvas');

canvas.add(new fabric.Text('hdgh', { 
    left: 20,
    top: 30, 
    fontFamily: 'Comic Sans MS',
    fontSize: 35
}));

canvas.add(new fabric.Text('foo', { 
  fontFamily: 'Roboto', 
  left: 100, 
  top: 100,
  fontSize: 25
}));

canvas.add(new fabric.Text('f776h', { 
  fontFamily: 'Arial', 
  left: 200, 
  top: 200,
  fontSize: 25
}));

that has 3 objects... Is there a way I can print on the console log (text, fontFamily, and fontSize) of each text object)

1 object - 'hdgh' ; Comic Sans MS ; 35 2 object - 'foo' ; Roboto ; 25 3 object - 'f776h' ; Arial ; 25
