Popping elements from the stack

Next, we are going to implement the pop method. This method is responsible for removing the items from the stack. As the stack uses the LIFO principle, the last item that we added is the one that is removed. For this reason, we can use the pop method from the JavaScript Array class that we also covered in the previous chapter. The pop method is represented as follows:

pop() {  return this.items.pop();} 

With the push and pop methods being the only methods available for adding and removing items from the stack, the LIFO principle will apply to our own Stack class.
