Method 1 - Ruby Convert Array to String Using the to_s Method

Ruby has a built-in to_s method that allows you to convert a given input type to string data type. Supported data types include: numbers, booleans, and hash. The function should return the output value as a string type.

Consider the example code shown below:

puts ['MySQL', 'PostgreSQL', 'Redis', 'Cassandra'].to_s


["MySQL", "PostgreSQL", "Redis", "Cassandra"]

Method 2 - Ruby Convert Array to String Using the join Method

Using the join method, we can convert an array to a string data type. The join method allows you to provide an input array and separator parameters. The method will then convert the elements of the array into individual string values based on the specified separator.


arr = [1,2,3,4,5]
puts arr.join(', ')


1, 2, 3, 4, 5

Method 3 - Ruby Convert Array to String Using Inspect Method

Ruby provides the inspect method which allows you to get a human-readable string for an input object such as an array.

Example demonstration is as shown:

arr = [1,2,3,4,5]
puts arr.inspect


["1", "2", "3", "4", "5"]


In this tutorial, you discovered quick and easy methods of converting an input array to string data type using Ruby built-in methods.
