Count the Number of Items in an Array in JavaScript

You can use length in order to count the number of items in an array in JavaScript:

var array = ["item1","item2",...];
array.length;

For example, you can use the following syntax to count the number of items in the array below:

var items = ["AA","BB","CC","DD","EE"];
items.length;

You’ll then get the count of 5 items using length.

Similarly, you can use this syntax to get a total count for the integers in the array:

var numbers = [2,5,33,22,9,12,45];
numbers.length;

In this case, you’ll get the count of 7 items.
