To create an array in JavaScript, simply assign values −

var animals = ["Dog", "Cat", "Tiger"];

You can also use the new keyword to create arrays in JavaScript −

var animals = new Array("Dog", "Cat", "Tiger");

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.
