linked-lists

Linked list exercises for The Odin Project

Instructions

You will need two classes or factories:

1. LinkedList class / factory, which will represent the full list.
2. Node class / factory, containing a value function 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

Testing

I have included my unit tests in this repository. They can be run by using jest.
