See what #npm packages your project is no longer using with this one-liner:
```sh
npx npm-check | grep -i 'notused?' | rev | cut -d'?' -f2 | cut -d' ' -f1 | rev
```
(Treat the list as a hint: [npm-check](https://www.npmjs.com/package/npm-check) isn't capable of detecting all possible usages of all packages, so there might be false positives.)
