To print object array in JavaScript, use JSON.stringify() method.
Example
You can try to run the following code to display object array −
<!DOCTYPE html> <html> <body> <pre id="test"></pre> <script> var data = [{ date: new Date(2017, 11, 25), value: 10 }, { date: new Date(2017, 11, 30), value: 20 }]; document.getElementById('test').innerHTML = JSON.stringify(data, null, 4); </script> </body> </html>
Output
[ { "date": "2017-12-24T18:30:00.000Z", "value": 10 }, { "date": "2017-12-29T18:30:00.000Z", "value": 20 } ]
