{{alias}}()
|
||
|
|
Stack constructor.
|
||
|
|
|
||
|
|
A stack is also referred to as a "last-in-first-out" queue.
|
||
|
|
|
||
|
|
Returns
|
||
|
|
-------
|
||
|
|
stack: Object
|
||
|
|
Stack data structure.
|
||
|
|
|
||
|
|
stack.clear: Function
|
||
|
|
Clears the stack.
|
||
|
|
|
||
|
|
stack.first: Function
|
||
|
|
Returns the "newest" stack value (i.e., the value which is "first-out").
|
||
|
|
If the stack is empty, the returned value is `undefined`.
|
||
|
|
|
||
|
|
stack.iterator: Function
|
||
|
|
Returns an iterator for iterating over a stack. If an environment
|
||
|
|
supports Symbol.iterator, the returned iterator is iterable. Note that,
|
||
|
|
in order to prevent confusion arising from stack mutation during
|
||
|
|
iteration, a returned iterator **always** iterates over a stack
|
||
|
|
"snapshot", which is defined as the list of stack elements at the time
|
||
|
|
of the method's invocation.
|
||
|
|
|
||
|
|
stack.last: Function
|
||
|
|
Returns the "oldest" stack value (i.e., the value which is "last-out").
|
||
|
|
If the stack is empty, the returned value is `undefined`.
|
||
|
|
|
||
|
|
stack.length: integer
|
||
|
|
Stack length.
|
||
|
|
|
||
|
|
stack.pop: Function
|
||
|
|
Removes and returns the current "first-out" value from the stack. If the
|
||
|
|
stack is empty, the returned value is `undefined`.
|
||
|
|
|
||
|
|
stack.push: Function
|
||
|
|
Adds a value to the stack.
|
||
|
|
|
||
|
|
stack.toArray: Function
|
||
|
|
Returns an array of stack values.
|
||
|
|
|
||
|
|
stack.toJSON: Function
|
||
|
|
Serializes a stack as JSON.
