JavaScript/Vue.js print object in the console

If you’re a web developer like me, you probably use console a lot. We use it to debug JavaScript code, to print out the contents of an object etc.

I use built-in Chrome tools, which is enough for most of the cases. I also use a Vue Devtools extension, when I build Vue.js apps, and I love it.

Here is a short and sweet tip on how to print JavaScript object using console.log().

How to print out content of JavaScript object

Suppose you have a JavaScript object:

var person = {
  name: 'Nedd',
  surname: 'Stark',
  child: {
    child1: 'child1Value'

To print out the content of person, you first need to stringify it using JSON.stringify() method.

str = JSON.stringify(person, null, 2); // it will also indent the output

Then pass it to console.log()


Your console output will be

JavaScript print object in console

If you need to reverse the operation use JSON.parse() method

person = JSON.parse(str);

Bonus console tips

#1 console.clear()

When your console log becomes too long you can clear its content using console.clear()

console.clear() function

#2 console.count()

If you want to count how many times your function has been called, you can use the console.count() function. It also takes an optional parameter “label”. Here is an example:

let user = "";

function greet() {
  return "hi " + user;

user = "bob";
user = "alice";

You’ll see output like this:

console.count() function

#3 console.table()

This one is my favourite, you can print a proper table with the objects using console.table() function.

var people = [
  { name: "Nedd", surname: "Stark" },
  { name: "Robb", surname: "Stark" }


You’ll see this beautiful table inside the console.
