stack-adt 
Stack ADT for browser and nodejs
The Stack class represents a last-in-first-out (LIFO) stack of generic items. It supports the usual push and pop operations, along with methods for peeking at the top item, testing if the stack is empty, and iterating through the items in LIFO order.
All stack operations except iteration and empty are constant time.

element
Type: object
the element to be pushed onto stack.
.pop() throws "Stack is empty" error
Removes and returns the top element from the stack.
Type: object
the element removed from the top of the stack.
.peek() throws "Stack is empty" error
Returns without removing the top element of the stack.
Type: object
the element on top of the stack.
.isEmpty()
Returns true if this stack contains no elements.
Type: boolean
whether or not the stack is empty.
.size()
Returns the number of elements in the stack.
Type: int
the number of element in the stack.
.empty()
Removes all element from the the queue and returns the new size of the queue.
.iterator
Returns an iterator to the stack that iterates through the items in LIFO order.
Type: object
the iterator object of the stack
.iterator.next() throws "No such element" error
Returns the next item in LIFO order.
.iterator.hasNext()
Returns whether the stack has next item in LIFO order.
