This answer doesn't describe what is happening. When you run npm test, the value of test gets run. So, in this case, we get a message printed to the screen and then our program exits.

While you can do this, you do not need to. You only need to do the following:

const moment = require('moment')

This will find the package in the node_modules/ folder by default.

const timenow = moment().format('LTS')
console.log(timenow)

- [ ] Move your `profile.js` file into a `src/` folder. Update the path in your `index.js` file to ensure everything continues to work.

const profile = require('./node_modules/moment/src/profile')
console.log(profile)
