Linked List

A practice implementation of a Linked List in JavaScript as an ES6 Class, based on the specifications at: https://www.theodinproject.com/lessons/javascript-linked-lists.

Usage

const list = new LinkedList();
list.append(1);
list.append(2);
console.log(list.toString()); // ( 1 ) -> ( 2 ) -> null;

The following class methods are implemented:

append(value) adds a new node containing value to the end of the list.
prepend(value) adds a new node containing value to the start of the list.
size() returns the total number of nodes in the list.
head() returns the first node in the list.
tail() returns the last node in the list.
at(index) returns the node at the given index.
pop() removes the last element from the list.
contains(value) returns true if the passed in value is in the list and otherwise returns false.
find(value) returns the index of the node containing value, or null if not found.
toString() returns the LinkedList objects as strings. The format is: ( value ) -> ( value ) -> ( value ) -> null
insertAt(value, index) inserts a new node with the provided value at the given index.
removeAt(index) removes the node at the given index.
search(searchFunction) returns the first item which satisfies the passed searchFunction
