    Type Parameters

    • T = number

    Parameters

    • Optional elements: T[]

_elements: T[]

Methods

clear

  • The clear function clears the elements array.

    Returns void

clone

  • The clone() function returns a new Stack object with the same elements as the original stack.

    Returns Stack<T>

    The clone() method is returning a new Stack object with a copy of the _elements array.

isEmpty

  • The function checks if an array is empty and returns a boolean value.

    Returns boolean

    A boolean value indicating whether the _elements array is empty or not.

peek

    Parameters

    • element: T

      The parameter "element" is of type T, which means it can be any data type.

    Returns Stack<T>

    The push method is returning the updated Stack<T> object.

size

  • The size() function returns the number of elements in an array.

    Returns number

    The size of the elements array.

toArray

  • The toArray function returns a copy of the elements in an array.

    Returns T[]

    An array of type T.

Static fromArray

  • The function "fromArray" creates a new Stack object from an array of elements.

    Type Parameters

    • T

    Parameters

    • elements: T[]

      The elements parameter is an array of elements of type T.

    Returns Stack<T>
