In the index.js file, make sure for every task's function, you return a new array/object with the updates needed.
You can run the tests to help guide you with the script npm test
in your terminal. Make sure that each of the tests passes before moving onto the next one.
- Make sure you
npm i
to install all of the packages that you need. - Work your way through the tasks in index.js. Don't worry about that fact that you can't see the arrays or items; they can all be found within the index.test.js file.
