Why does the package keep downloading this package-lock.json file? It doesn't show this file in Andrew's folder structer.

This file describes an exact, and more importantly reproducible node_modules tree. Once it's present, any future installation will base its work off this file, instead of recalculating dependency versions off package.json.
I can safely deduce this course was recorded before npm 5 was released. Thus, package-lock.json hadn't existed yet.

package.json. Thepackage-lock.jsonis optional and is generated based on thepackage.jsondependencies.
