Final Answer:
To delete the last element of the row array printqueue, we can use the pop() method.
Explanation:
The pop() method in JavaScript is used to delete the last element from an array. This method does not take any arguments and always returns the removed element from the array. Therefore, by using the pop() method we can delete the last element from the row array printqueue.
The syntax for the pop() method is array.pop(), where array is the name of the array from which the element is to be removed. In this case, the array is printqueue, so the correct syntax is printqueue.pop(). This method will remove the last element from the row array printqueue and return the element that was removed.
Using the pop() method is a simple way to delete the last element of a row array. It is also a convenient way as it is a single line of code and is easy to remember. The pop() method is also faster than many other methods as it does not require any arguments and returns the removed element.
The pop() method is also a non-destructive method, meaning that it does not modify the original array. Instead, it creates a copy of the array and then removes the element from the copy. This is useful if we want to keep a backup of the original array.
In conclusion, the pop() method is an efficient way to delete the last element of a row array. It is simple to use and does not require any arguments. It is also a non-destructive method and returns the removed element from the array.
