To run the tests:

• Inside of the root folder, run command npm install to install node packages
• Open index.js to find the javascript functions to complete
• Instructions are found inside each function
• Run npm run test to automatically open index.html in a browser
  • After completing a function or enabling a new test, refresh the page for the test to run again
• Open index.test.js and remove the x from each test suite you want to run
  • xdescribe (inactive) ---> describe (active)
  • The first test getAllElementsButNth is already active for you as an example
• There are multiple unit tests testing edge cases and other expectations for each function to be completed
• Active tests will be red until you complete the function
• Once you fulfill the requirements for the tests, you will see green dots, hooray!
