## Overview
The **`to_a` method** is called on an array in Ruby to return the same array. When it is called on an object, it converts the object to an array.

## Syntax
The syntax of the `to_a` is given below:
```ruby
arr.to_a
```

## Parameters
**arr**: This is the array object that we want to convert.

## Return value
It returns an array that is the same as `arr`.

## Example
In the example below, we will demonstrate the use of the `to_a` on arrays. We will see that the same array is returned.

# create arrays
arr1 = [1, 2, 3, 4, 5]
arr2 = ["a", "b", "c", "d", "e"]

# call to_a on the arrays
a = arr1.to_a
b = arr2.to_a

# print the returned values
puts "#{a}"
puts "#{b}"

## Explanation
* Lines 2-3: We create two arrays, `arr1` and `arr2`.
* Lines 6-7: We call the `to_a` method on the arrays we created and store the results inside variables `a` and `b`.
* Lines 10-11: We print the results to the console.
As we have seen above, the `to_a` returns the same elements of the array.
