Methods

clear()

linkedList/linkedList.js, line 223

Resets the Linked List

Example

const { LinkedList } = require('data-structures-algorithms-js');
const linkedList = new LinkedList();

linkedList.push(15);

linkedList.clear(); // now linked list is empty

getElementAt(index) → {*|undefined}

linkedList/linkedList.js, line 99

Returns a element from a specific index if it exists

Parameters:

Name	Type	Description
index	*	Index passed to return element

Returns:

* | undefined -

Returns the element or undefined

Example

const { LinkedList } = require('data-structures-algorithms-js');
const linkedList = new LinkedList();

linkedList.push(3);
linkedList.push(9);

linkedList.getElementAt(1); //returns number 9

head() → {Object}

linkedList/linkedList.js, line 194

Returns the nodo on the head of the linked list

Returns:

Object -

returns the head object with the element and next node

Example

const { LinkedList } = require('data-structures-algorithms-js');
const linkedList = new LinkedList();


linkedList.push(23);

linkedList.head(); //returns {element:23, next:null};

indexOf(element) → {Number}

linkedList/linkedList.js, line 156

Returns the index of a specific element if it exists

Parameters:

Name	Type	Description
element	*	Element passed to find the index

Returns:

Number -

Returns the index or -1

Example

const { LinkedList } = require('data-structures-algorithms-js');
const linkedList = new LinkedList();

linkedList.push(3);
linkedList.push(9);

linkedList.indexOf(5); //returns -1
linkedList.indexOf(3); //returns 0

insert(element, index)

linkedList/linkedList.js, line 124

Inserts a element to the specific position of the linked list

Parameters:

Name	Type	Description
element	*	Element passed to insert
index	Number	Index to insert

Example

const { LinkedList } = require('data-structures-algorithms-js');
const linkedList = new LinkedList();

linkedList.push(5);
linkedList.push(7);

linkedList.insert(15, 1); // inserts 15 at index 1

isEmpty() → {Boolean}

linkedList/linkedList.js, line 210

Returns if the linked list is empty

Returns:

Boolean

Example

const { LinkedList } = require('data-structures-algorithms-js');
const linkedList = new LinkedList();

linkedList.isEmpty(); // returns true;

linkedList.push(23);

linkedList.isEmpty(); //returns false;

push(element)

linkedList/linkedList.js, line 26

Adds a element to the end of the linked list

Parameters:

Name	Type	Description
element	*	Element passed to insert

Example

const { LinkedList } = require('data-structures-algorithms-js');
const linkedList = new LinkedList();

linkedList.push(5); //inserts 5 to the end of the linked list

remove(element) → {*|undefined}

linkedList/linkedList.js, line 52

Removes a element if it exists

Parameters:

Name	Type	Description
element	*	Element passed to remove

Returns:

* | undefined -

Returns the removed element or undefined

Example

const { LinkedList } = require('data-structures-algorithms-js');
const linkedList = new LinkedList();

linkedList.push(3);
linkedList.push(9);

linkedList.remove(3); //removes and returns number 3

removeAt(element) → {*|undefined}

linkedList/linkedList.js, line 70

Removes a element from a specific index if it exists

Parameters:

Name	Type	Description
element	*	Element passed to remove

Returns:

* | undefined -

Returns the removed element or undefined

Example

const { LinkedList } = require('data-structures-algorithms-js');

linkedList.push(3);
linkedList.push(9);

linkedList.removeAt(1); //removes and returns number 9

size() → {Number}

linkedList/linkedList.js, line 179

Returns the size of the Linked List

Returns:

Number -

The number of elements in the Linked List

Example

const { LinkedList } = require('data-structures-algorithms-js');
