Final answer:
The pop() command removes and returns the last element of an array, shortening the array by one element. It is typically used in programming languages such as JavaScript and modifies the original array.
Step-by-step explanation:
The pop() command is used in many programming languages to remove the last element from an array. When you use pop(), it not only removes the last element but also returns it. This can be useful if you need to work with that element after removing it from the array. The array is then shortened by one element.
The pop() method removes the last element from an array and returns that value to the caller. The pop() method removes the specified item from the dictionary. The value of the removed item is the return value of the pop() method, see example below.Transferring messages from an e-mail server to an e-mail client is the use of POP (Post Office Protocol). POP is the primary protocol behind email communication.
In languages like JavaScript, you can use pop() simply by appending it to the end of an array variable like so:let fruits = ['apple', 'banana', 'cherry']; let lastFruit = fruits.pop(); // fruits is now ['apple', 'banana'] // lastFruit is 'cherry'.
