In Ruby, **`array.reverse()`** is a method that reverses an array but does not change the original array. Instead, it returns a new array that contains the original array's elements in reverse order.

#     
## Syntax
```ruby
array.reverse()
```

## Parameters
This method does not take any parameters. It only requires the array instance.

## Return value
The `reverse()` method returns a new array that contains the elements of the instance array in reverse order.


# creating array instances
array1 = [1, 2, 3, 4, 5]
array2 = ["a", "b", "c", "d", "e"]
array3 = ["Javascript", "Python", "Java", "C++", "Ruby"]

# printing their reverse form using `reverse()` method
puts "#{array1} in reverse = #{array1.reverse()}"
puts "#{array2} in reverse = #{array2.reverse()}"
puts "#{array3} in reverse = #{array3.reverse()}"


> Note: The `reverse()` method does not overwrite or change the original array.


array = [1, 2, 3, 4, 5]
reversedArray = array.reverse()

puts "#{reversedArray}\n"
puts "#{array}\n"

In the above code, we see that the original array remains the same.

What is array.reverse() in Ruby?

Reverse in Ruby returns a new array with the elements in reverse order, leaving the original unchanged.
