Creating an Array

Using an array literal is the easiest way to create a JavaScript Array. The syntax looks like this:

  var array-name = [item1, item2, ...];

An example of an actual array looks like this:

var cars = ["Saab", "Volvo", "BMW"];

Using the JavaScript Keyword new

The following example also creates an array, and assigns values to it:

var cars = new Array("Saab", "Volvo", "BMW");

The two examples above do exactly the same. There is no need to use new Array(). For simplicity, readability and execution speed, use the first one (the array literal method).
