This project contains a skeleton for you to implement a linked list. This is a test-driven project. Run the tests and read the top-most error. If it's not clear what is failing, open the test/test.js file to figure out what the test is expecting. Make the top-most test pass.

Keep making the top-most test pass until all tests pass.

• cd into the project folder
• npm install to install dependencies in the project root directory
• mocha to run the specs
• You can view the test cases in /test/test.js. Your job is to write code in the /lib/linked_list.js that implements the Node and LinkedList classes to make the tests pass.
