# Simple Linked List Write a simple linked list implementation that uses Elements and a List. The linked list is a fundamental data structure in computer science, often used in the implementation of other data structures. They're pervasive in functional programming languages, such as Clojure, Erlang, or Haskell, but far less common in imperative languages such as Ruby or Python. The simplest kind of linked list is a singly linked list. Each element in the list contains data and a "next" field pointing to the next element in the list of elements. This variant of linked lists is often used to represent sequences or push-down stacks (also called a LIFO stack; Last In, First Out). As a first take, lets create a singly linked list to contain the range (1..10), and provide functions to reverse a linked list and convert to and from arrays. When implementing this in a language with built-in linked lists, implement your own abstract data type. ## Setup Go through the setup instructions for JavaScript to install the necessary dependencies: http://exercism.io/languages/javascript/installation ## Running the test suite The provided test suite uses [Jasmine](https://jasmine.github.io/). You can install it by opening a terminal window and running the following command: ```sh npm install -g jasmine ``` Run the test suite from the exercise directory with: ```sh jasmine simple-linked-list.spec.js ``` In many test suites all but the first test have been marked "pending". Once you get a test passing, activate the next one by changing `xit` to `it`. ## Source Inspired by 'Data Structures and Algorithms with Object-Oriented Design Patterns in Ruby', singly linked-lists.
