**`pop()`** is a Ruby array method that pops or removes the last element of a given array. It permanently removes the last element of an array.

#     
## Syntax
```ruby
array.pop(noOfElements)
```

## Parameter
**`noOfElements`**: This is the number of elements to be removed from the end of the array. If it is not specified, only the last element will be removed and returned.

## Return Value
The returned value is the element or elements that were removed.

## Example
In the example below, we create an array and use the `pop()` method.



# Initializing some arrays of elements
arr = [1, 2, 3, 4, 5, 6, 7]
  
# Calling pop() function
A = arr.pop() 
B = arr.pop(2)
C = arr.pop(3)
D = arr
  
# Printing the removed elements 
puts "#{A}"
puts "#{B}"
puts "#{C}"
  
# Printing the remaining array
puts "#{D}"
