Declaring multiple variables in JavaScript

Question

In JavaScript, it is possible to declare multiple variables like this:

var variable1 = "Hello, World!";
var variable2 = "Testing...";
var          


        

Answer 1

var variable1 = "Hello, World!";
var variable2 = "Testing...";
var variable3 = 42;

is more readable than:

var variable1 = "Hello, World!",
    variable2 = "Testing...",
    variable3 = 42;

But they do the same thing.
