JavaScript Array Reference


Array Object

The Array object is used to store multiple values in a single variable:

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

Array indexes are zero-based: The first element in the array is 0, the second is 1, and so on.

For a tutorial about Arrays, read our JavaScript Array Tutorial.
