Linked Lists

Description

This project is part of The Odin Project - Full Stack JavaScript Path. The main goal here is to implement and work with a custom data structure: linked list.

Technologies

• JavaScript
• Npm
• Git

Assignment

You will need two classes or factories:

• LinkedList class / factory, which will represent the full list.
• Node class / factory, containing a value property and a link to the nextNode, set both as null by default.

Build the following functions in your linked list class:

• 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 represents your LinkedList objects as strings, so you can print them out and preview them in the console. The format should be: ( value ) -> ( value ) -> ( value ) -> null

Extra Credit

• insertAt(value, index) that inserts a new node with the provided value at the given index.
• removeAt(index) that removes the node at the given index.

Extra Credit Tip: When you insert or remove a node, consider how it will affect the existing nodes. Some of the nodes will need their nextNode link updated.
