Whitespace in javascript

Something Like that:
Whitespace

What is Whitespace?
Invisible characters that create literal ‘space’ in your written code
(carriage return, tabs, space)
basically Whitespace means clean code with comments for easy understand to coder

There are two examples and both are correct

For that you need to create first html code.

HTML

<p id="demo1"></p>

After that add this JS code.

JS

var firstname, lastname, lang;
var person = {firstname: 'John', lastname: 'Doe'}

document.getElementById("demo1").innerHTML = person;

Now you can see

[object Object]

Now next example with clean code

For that you need to create first html code.

HTML

<p id="demo1"></p>

After that add this JS code.

JS

var 
    // first name of the person
    firstname,

    // last name of the person
    lastname,

    // the lang
    // can be 'en' or 'es'
    lang;

var person = {
    // the first name
    firstname: 'John',

    // the last name
    // (always required)
    lastname: 'Doe'
}

document.getElementById("demo1").innerHTML = person;

This is the best way to write code.
Now you can see
