How to get length of an array in Ruby

In this tutorial, we will learn how to get the length of an array in Ruby.

The length of an array means the total number of elements present in a given array.

Using length method

To get the length of an array, we can use the built-in length method in Ruby.

The length method returns the number of elements in an array in integer format.

Here is an example, that gets the length of a prices array:

prices = [10, 40, 80]
length = prices.length

puts length

Output:

3

Alternatively, we can also use the size method in ruby to get the length of an given array.

prices = [10, 40, 80]
length = prices.size

puts length
