To create an array of integers in JavaScript, try the following −

var rank = [1, 2, 3, 4];

You can also use the new keyword to create array of integers in JavaScript −

var rank = new Array(1, 2, 3, 4);

The Array parameter is a list of strings or integers. When you specify a single numeric parameter with the Array constructor, you specify the initial length of the array. The maximum length allowed for an array is 4,294,967,295.
